Abstract
Cockayne's syndrome (CS) is a rare autosomal recessive multisystem disease characterised by early severe progression of symptoms. This study reports the feasibility of earlier prenatal diagnosis of CS by coelocentesis at 8 weeks of gestation respect to amniocentesis or villocentesis. Three couples at risk for CS asked to perform prenatal diagnosis by coelocentesis. Coelomic fluid was aspired from coelomic cavity in four singleton pregnancy at 8 weeks of gestation and 40 foetal cells were recovered by micromanipulator. Maternal DNA contamination was evaluated by quantitative fluorescent PCR (QF-PCR) and target regions of foetal DNA containing parental mutations of ERCC6 gene were amplified and sequenced. In all these cases, molecular analysis was possible. One foetus resulted affected of CS and the diagnosis was confirmed on placental tissue after voluntary abortion. In three cases, foetuses resulted carrier of a parental mutation and the results were confirmed after the birth. This study suggests that reliable prenatal diagnosis of CS could be performed using foetal cells present in coelomatic fluid in earlier pregnancy. Coelocentesis could be applied in prenatal diagnosis of CSs as well as for other monogenic diseases, at very early stage of pregnancy, if parental mutations are already known.Impact StatementWhat is already know on this subject? Previous studies utilising coelocentesis for prenatal determination of foetal sex reported variable success ranging from 58% to 95%, because of low total DNA content and presence of maternal cell contamination. This procedure has never been reported for early prenatal diagnosis at 8 weeks of gestation for rare genetically transmitted diseases such as Cockayne's syndrome.What do the results of this study add? This study demonstrates that coelomic fluid sampling combined with well-standardised laboratory procedures can be applied for prenatal diagnosis at eight weeks of gestation for any rare monogenic disease if molecular defects are known.What are the implications of these findings for clinical practice and/or further research? The findings of this study in at risk couples for monogenic diseases investigated by coelocentesis demonstrate that embryo-foetal cell selection from CF allows reliable and early prenatal diagnosis of diseases. This technique is attractive to parents because it provides prenatal diagnosis of genetic disease at least 4 weeks earlier than what can be achieved by the traditional procedures reducing anxiety of parents and provides the option for medical termination of affected cases at 8-10 weeks' gestation, which is less traumatic and safer than second-trimester surgical termination. Further research concerns the possibility to obtain foetal karyotype at eight weeks of gestation and the possibility of intrauterine corrective therapy.

Abstract
A fetal sonographic screening examination performed at 23 weeks showed polyhydramnios, micrognathia, fixed postures of all long bones, but no movement and no breathing. The fetus showed fetal heart rate acceleration but no movement when acoustic stimulation was applied with artificial larynx. All these findings persisted on serial examinations. The neonate was stillborn at 37 weeks and a final diagnosis of Pena-Shokeir sequence was made. In addition to typical sonographic features of Pena-Shokeir sequence, fetal heart rate accelerations with no movement in response to acoustic stimulation suggests that peripheral myopathy may possibly play an important role in the pathogenesis of the disease. © 2016 Wiley Periodicals, Inc.

Abstract
Warburg syndrome is a rare disorder characterized by microcephaly, microcornea, congenital cataract, developmental delay, and hypogonadism. Here, we report two siblings from India who presented with developmental delay, microcornea, microphthalmia, and bilateral congenital cataracts, born to the third-degree consanguineously married couple. Both children had hypoplasia of corpus callosum. In this report, we aim to highlight and compare clinical features of these two cases with previously reported cases.

Abstract
Tubulinopathies are increasingly emerging major causes underlying complex cerebral malformations, particularly in case of microlissencephaly often associated with hypoplastic or absent corticospinal tracts. Fetal akinesia deformation sequence (FADS) refers to a clinically and genetically heterogeneous group of disorders with congenital malformations related to impaired fetal movement. We report on an early foetal case with FADS and microlissencephaly due to TUBB2B mutation. Neuropathological examination disclosed virtually absent cortical lamination, foci of neuronal overmigration into the leptomeningeal spaces, corpus callosum agenesis, cerebellar and brainstem hypoplasia and extremely severe hypoplasia of the spinal cord with no anterior and posterior horns and almost no motoneurons. At the cellular level, the p.Cys239Phe TUBB2B mutant leads to tubulin heterodimerization impairment, decreased ability to incorporate into the cytoskeleton, microtubule dynamics alteration, with an accelerated rate of depolymerization. To our knowledge, this is the first case of microlissencephaly to be reported presenting with a so severe and early form of FADS, highlighting the importance of tubulin mutation screening in the context of FADS with microlissencephaly.

Abstract
Mutations in XPD cause xeroderma pigmentosum (XP), XP and Cockayne syndrome (CS) crossover syndrome (XP/CS), trichothiodystrophy and cerebro-oculo-facio-skeletal syndrome (COFS). COFS represents the most severe end of the CS spectrum. This study reports two Japanese patients, COFS-05-135 and COFS-Chiba1, who died at ages of <1 year and exhibited typical COFS manifestations caused by XPD mutations p.[I619del];[R666W] and p.[G47R];[I619del], respectively. Two other cases of severe XP-D/CS (XP group D/CS), XP1JI (p.[G47R];[0]) and XPCS1PV (p.[R666W];[0]), died at ages <2 years. On the other hand, two cases of mild XP-D/CS, XP1NE (p.[G47R];[L461V;V716_R730del]) and XPCS118LV (p.[L461V;V716_R730del];[R666W]), lived beyond 37 years of age. p.I619Del and p.[L461V;V716_R730del] are functionally null; therefore, despite the differences in clinical manifestations, the functional protein in all of these patients was either p.G47R or p.R666W. To resolve the discrepancies in these XPD genotype-phenotype relationships, the p.[L461V;V716_R730del] allele was analyzed and we found that p.[L461V;A717G] was expressed from the same allele as p.[L461V;V716_R730del] by authentic splicing. Additionally, p.[L461V;A717G] could partially rescue the loss of XPD function, resulting in the milder manifestations observed in XP1NE and XPCS118LV.

Mutations in ERCC6 are associated with growth failure, intellectual disability, neurological dysfunction and deterioration, premature aging, and photosensitivity. We describe siblings with biallelic ERCC6 mutations (NM_000124.2:c. [543+4delA];[2008C>T]) and brain hypomyelination, microcephaly, cognitive decline, and skill regression but without photosensitivity or progeria. DNA repair assays on cultured skin fibroblasts confirmed a defect of transcription-coupled nucleotide excision repair and increased ultraviolet light sensitivity. This report expands the disease spectrum associated with ERCC6 mutations.

Abstract
Transcriptional arrest caused by DNA damage is detrimental for cells and organisms as it impinges on gene expression and thereby on cell growth and survival. To alleviate transcriptional arrest, cells trigger a transcription-dependent genome surveillance pathway, termed transcription-coupled nucleotide excision repair (TC-NER) that ensures rapid removal of such transcription-impeding DNA lesions and prevents persistent stalling of transcription. Defective TC-NER is causatively linked to Cockayne syndrome, a rare severe genetic disorder with multisystem abnormalities that results in patients' death in early adulthood. Here we review recent data on how damage-arrested transcription is actively coupled to TC-NER in mammals and discuss new emerging models concerning the role of TC-NER-specific factors in this process.

Abstract
Cockayne syndrome is a progressive multisystem disorder characterized by a specific cellular defect in transcription-coupled repair. Typical features include developmental delay, failure to thrive, microcephaly, cutaneous photosensitivity, dental anomalies, progressive hearing loss, pigmentary retinopathy, cataracts and enophthalmia. Various levels of severity have been described including the "classical" or moderate type I CS, the early-onset or severe type II and the mild or late-onset type III. Adult-onset cases with prolonged survival and normal initial development have also been identified. At the opposite end of the scale, the most severely affected patients, showing a prenatal onset of the symptoms, are overlapping with the cerebro-oculo-facio-skeletal (COFS) syndrome. These overlapping subtypes build a continuous spectrum without clear thresholds. Revised diagnostic criteria are proposed to improve the recognition of the disease. Two thirds of the patients are linked to mutations in the CSB (ERCC6) gene, one third to mutations in the CSA (ERCC8) gene. At least 78 different mutations are known in the CSB gene and 30 in the CSA gene to date, in more than 120 genetically confirmed patients. Large clinical and molecular databases are needed to unravel genotype-phenotype correlations and to gain more insight into the underlying molecular mechanisms.

Abstract
Pena-Shokeir syndrome is a rare, early lethal disease. It is characterized by fetal growth restriction; craniofacial deformities, for example micrognathia and microcephaly; multiple ankyloses; and pulmonary hypoplasia. For patients with this syndrome, maintenance of airway and control of perioperative respiratory complications are important for anesthetic management. We report 3 pediatric cases of Pena-Shokeir syndrome undergoing tracheostomy and arthrolysis under general anesthesia using sevoflurane, nitrous oxide, fentanyl, and vecuronium bromide. Anesthetic procedures including mask ventilation, tracheal intubation, and extubation were successfully performed without complications during and after surgery. In patients with Pena-Shokeir syndrome, inhalational anesthetics can be safely used for induction and maintenance of anesthesia, although it is important to assume that difficult airway management might be encountered.

Abstract
ERCC1-XPF is a structure-specific endonuclease required for nucleotide excision repair, interstrand crosslink repair, and the repair of some double-strand breaks. Mutations in ERCC1 or XPF cause xeroderma pigmentosum, XFE progeroid syndrome or cerebro-oculo-facio-skeletal syndrome, characterized by increased risk of cancer, accelerated aging and severe developmental abnormalities, respectively. This review provides a comprehensive overview of the health impact of ERCC1-XPF deficiency, based on these rare diseases and mouse models of them. This offers an understanding of the tremendous health impact of DNA damage derived from environmental and endogenous sources.

Abstract
Cockayne syndrome (CS) is a rare degenerative disorder with a common set of symptoms but a very wide variation in phenotype. The variation is sufficiently wide that CS patients have traditionally been described in three different severity groups. Unfortunately, there is no single source for information about the different severity groups. This problem can complicate not only diagnosis, but accurate prognosis as well. The goal of this study was to describe the phenotypic variation in CS as completely as possible. This article provides extensive descriptions of traits common to each group and their degree of severity in each group. Forty-five people with CS were surveyed and information from the published literature was used to increase the sample sizes for calculations. This study provides new information, including statistical data for each of the three severity groups (mean age at death, average head circumference, and average length or stature). The study includes cerebro-oculo-facial syndrome (COFS) as a severe form of CS, based on results of recently published genetic studies performed by other authors. This study proposes revised names for CS severity groups: severe, moderate, and mild. The groups were formerly called Type II/early onset CS, Type I/classical CS, and Type III/atypical/mild/late-onset CS, respectively. A fourth newly documented group, UV sensitivity only/adult onset, is also described. Average ages of death were calculated as 5.0 years (severe), 16.1 years (moderate), and 30.3 years (mild).

Abstract
OBJECTIVE In view of the increasing role of magnetic resonance imaging (MRI) as an adjunct to prenatal ultrasonography (US), this study sought to demonstrate the visualization of fetal akinesia and associated abnormalities on MRI. METHODS This retrospective study included six fetuses with akinesia and associated abnormalities, depicted on fetal MRI after suspicious prenatal US. The whole fetus was assessed for musculoskeletal abnormalities and associated pathological conditions elsewhere. Fetal outcome data were compared with prenatal imaging. US and MRI findings were also compared. RESULTS Akinesia resulting in arthrogryposis was seen in 6/6 fetuses, with abnormal musculature in 5/6 fetuses. Associated brain abnormalities were found in 2/6 fetuses; facial abnormalities in 3/6; lung hypoplasia in 3/6; and polyhydramnios in 2/6. There were 5/6 pregnancies that were terminated and one individual died neonatally. MRI and brain autopsy were concordant in 4/6 cases. MRI and body autopsy were concordant in 1/6 cases and in 5/6 cases, autopsy revealed additional abnormalities. In addition to US, MRI correctly identified central nervous system findings in four cases and lung hypoplasia in three cases. CONCLUSION Our MRI results demonstrate fetal akinesia and associated abnormalities, which may have an impact on perinatal management, as an adjunct to prenatal US.

Abstract
Cerebro-oculo-facio-skeletal (COFS) syndrome is an autosomal recessive disorder characterized by microcephaly, congenital cataracts, facial dysmorphism, neurogenic arthrogryposis, growth failure and severe psychomotor retardation. We report a large consanguineous pedigree from northern Finland with six individuals belonging into four different sibships and affected with typical COFS syndrome phenotype. Two deceased patients have been published previously in 1982 as the first cases exhibiting cerebral calcifications typical for this disorder. Two living and one of the deceased patients were all shown to possess a novel homozygous mutation in the ERCC6 [Cockayne syndrome B (CSB)] gene, thereby confirming the diagnosis on molecular genetic level even for the earlier published cases. Genealogical investigation showed a common ancestor living in a northeastern village in Finland in the 18th century for all six patients implying a founder effect.

Abstract
Cerebro-oculo-facio-skeletal (COFS) syndrome is an autosomal recessive inherited disorder characterized by congenital microcephaly, congenital cataracts and/or microphthalmia, arthrogryposis, severe developmental delay, severe postnatal growth failure and facial dysmorphism with prominent nasal root and/or overhanging upper lip. This syndrome is now recognized as a disorder belonging to the spectrum of inherited defects in Nucleotide Excision Repair (NER) resulting in profound photosensitivity. In COFS syndrome, as in Cockayne syndrome, DNA repair is impaired in the transcription-coupled NER pathway, but not in the global genome NER pathway. Fourteen cases so far described as COFS syndrome have been studied at the molecular levels. All mutations have been found in Cockayne syndrome gene, CSB, xeroderma pigmentosum genes, XPD and XPG and ERCC1 gene involved in the transcription-coupled NER pathway.

Abstract
Cockayne syndrome and xeroderma pigmentosum-Cockayne syndrome complex are rare autosomal recessive disorders with poorly understood biology. They are characterized by profound postnatal brain and somatic growth failure and by degeneration of multiple tissues resulting in cachexia, dementia, and premature aging. They result in premature death, usually in childhood, exceptionally in adults. This study compares the clinical course and pathology of a man with Cockayne syndrome group A who died at age 31(1/2) years with 15 adequately documented other adults with Cockayne syndrome and 5 with xeroderma pigmentosum-Cockayne syndrome complex. Slowing of head and somatic growth was apparent before age 2 years, mental retardation and slowly progressive spasticity at 4 years, ataxia and hearing loss at 9 years, visual impairment at 14 years, typical Cockayne facies at 17 years, and cachexia and dementia in his twenties, with a retained outgoing personality. He experienced several transient right and left hemipareses and two episodes of status epilepticus following falls. Neuropathology disclosed profound microencephaly, bilateral old subdural hematomas, white-matter atrophy, tigroid leukodystrophy with string vessels, oligodendrocyte proliferation, bizarre reactive astrocytes, multifocal dystrophic calcification that was most marked in the basal ganglia, advanced atherosclerosis, mixed demyelinating and axonal neuropathy, and neurogenic muscular atrophy. Cellular degeneration of the organ of Corti, spiral and vestibular ganglia, and all chambers of the eye was severe. Rarely, and for unexplained reasons, in some patients with Cockayne syndrome the course is slower than usual, resulting in survival into adulthood. The profound dwarfing, failure of brain growth, cachexia, selectivity of tissue degeneration, and poor correlation between genotypes and phenotypes are not understood. Deficient repair of DNA can increase vulnerability to oxidative stress and play a role in the premature aging, but why patients with mutations in xeroderma pigmentosum genes present with the Cockayne syndrome phenotype is still not known.

Abstract
Neu-Laxova syndrome (NLS) is a rare autosomal recessive syndrome, characterized by severe intrauterine growth retardation (IUGR), microcephaly, abnormal brain development, oedema and ichthyosis. It was first reported in 1971 by Neu et al. (Pediatrics 47: 610-612) and since then no more than 60 cases have been reported. A newborn girl delivered from a 29-year-old healthy mother was admitted to hospital with a thick membrane covering her body and dismorphic appearance. The diagnosis of NLS was made according to characteristic features. The syndrome is known to have a poor prognosis and the baby lived for 9 weeks. This case is one of the longest living cases of NLS and the fourth case reported from Turkey.

Abstract
Children born with the findings of microcephaly, cataracts and microcornea can result not only from a prenatal viral infection, but also from an autosomal recessive Mendelian disorders. We present three pairs of affected siblings with MICRO syndrome, who were born with congenital microcephaly, microcornea, and cataracts. MICRO syndrome is an autosomal recessive syndrome consisting of congenital microcephaly, cortical dysplasia, microcornea, cataracts, optic atrophy, severe mental retardation, hypotonic diplegia, and hypogenitalism. At birth, MICRO syndrome resembles Cerebro-Oculo-Facio-Skeletal (COFS) syndrome, but it differs in the lack of the rapidly progressive neurologic features leading to severe brain atrophy with calcifications. Patients with MICRO syndrome manifest frontal cortical dysplasia, hypoplasia of the corpus callosum, cortical blindness with optic atrophy, profound mental retardation, and progressive joint contractures with growth failure. COFS syndrome shares also many clinical and cellular similarities with Cockayne syndrome (CS), and cultured cells in both conditions demonstrate hypersensitivity to ultraviolet (UV) radiation due to impaired nucleotide excision repair (NER). NER studies in cultured fibroblasts from MICRO patients give normal results, so MICRO syndrome should be considered in children with features resembling COFS syndrome and CS, but who have normal NER. MICRO should be distinguished from other similar clinical disorders with normal NER by the presence of significant visual impairment and cortical blindness despite early surgery for congenital cataracts, frontal polymicrogyria, thin corpus callosum, and cortical atrophy by MRI.

Abstract
We report a 14-year-old male, born to consanguineous parents, with microcephaly, intracranial calcification, severe mental retardation, cataracts, optic atrophy, pigmentary retinopathy, contractures, scoliosis, and failure to thrive. His brain imaging revealed extensive basal ganglia calcifications. He has normal ultraviolet sensitivity. These features are consistent with the autosomal recessive cerebro-oculo-facio-skeletal syndrome. In addition, he has severe muscle weakness with end-stage muscle changes on biopsy. There have been few reports of muscle involvement in cerebro-oculo-facio-skeletal syndrome, and this is the first time it has been described in a cerebro-oculo-facio-skeletal patient with normal ultraviolet sensitivity. This case extends the extensive phenotypic similarities between cerebro-oculo-facio-skeletal syndrome patients with and without abnormal ultraviolet sensitivity, and highlights the cerebro-oculo-facio-skeletal syndrome in the differential diagnosis of congenital muscular dystrophies.

Abstract
PURPOSE To report the ocular findings in cerebro-oculo-facial-skeletal syndrome or Pena-Shokeir-II syndrome. METHODS Case report. RESULTS A five-month-old male infant presented with bilateral posterior polar cataract, microphthalmos, nystagmus, and marked non-glaucomatous optic nerve atrophy. Systemic abnormalities such as microcephaly, micrognathia, flexion contractures of the elbows and knees, hypotonic musculature, and failure to thrive, with pronounced statomotor retardation, led to the diagnosis of cerebro-oculo-facial-skeletal syndrome or Pena-Shokeir-II syndrome. Cataract surgery did not improve the poor visual performance. CONCLUSIONS Cerebro-oculo-facial-skeletal syndrome (Pena-Shokeir-II syndrome) should be included in the differential diagnosis of bilateral microphthalmos, congenital cataract, nystagmus, and pronounced optic nerve atrophy, and cataract surgery does not markedly improve vision.

Abstract
The field of developmental neurogenetics has burgeoned over the past decade. Through the combined efforts of developmental biologists, geneticists, and clinicians, genetic defects resulting in neuro-ophthalmic disorders such as holoprosencephaly, microphthalmia, dominant optic atrophy, and optic nerve colobomas have been identified and characterized at the molecular level. Experimental studies in model organisms are continuing to identify novel genes critical for ocular and central nervous system development. Mutations in some of these genes have revealed a spectrum of pathology similar to that observed in septo-optic dysplasia, Möebius syndrome, and Duane retraction syndrome. This review examines our current knowledge of the molecular genetics of neuro-ophthalmic disease and focuses on several candidate genes for afferent and efferent visual system disorders.

Abstract
We report three sisters showing the clinical features and investigational findings of Cockayne syndrome (CS). In the rehabilitation unit of Northwest Armed Forces Hospital (N.W.A.F.H.), Tabuk, Saudi Arabia, there was a 12-year-old girl with typical features of CS. The girl had no apparent problems until the end of the first year when growth and developmental delay prompted medical evaluation. Brain CT, bone X-rays, auditory and ophthalmological evaluation confirmed the clinical impression of Cockayne syndrome. Two of her 13 sibs, both sisters, were later found to have the same syndrome. The sisters varied in clinical severity, as two of them had cataracts and early global delay and died early of inanition and infection. The third showed the disease manifestations at a relatively later age, did not have cataract, exhibited milder manifestations of the disease, and remains alive. The parents are not related by any way and the father is married to two other wives with 11 unaffected children. This report documents variable degrees of manifestations in sibs who presumably have the same gene mutation.

Abstract
Pena-Shokier phenotype is an early lethal disorder involving multiple joint contractures, facial anomalies, and pulmonary hypoplasia. Alternative terms for this syndrome used in the literature include fetal hypokinesia syndrome, lethal congenital contracture syndrome, and Pena-Shokier syndrome type I. The etiology for the early cases was attributed to neuromuscular disease, with deformations owing to weakness or paralysis of the motor unit. An abnormality of spinal cord motoneurons has been postulated in some cases. Pena-Shokier phenotype can also result from blockade of the neuromuscular junction, as shown by recent observations with women expressing antibodies against the fetal acetylcholine receptor. It has been shown that the Pena-Shokier phenotype may result from intrauterine cerebral dysfunction as well, including acquired brain insults and congenital brain malformations. The ultimate prognosis for children with this disorder is dependent on the underlying etiology and the severity of pulmonary disease. The authors report a fatal case of Pena-Shokier phenotype with congenital polymicrogyria. To our knowledge, the case presented is the first reported Pena-Shokier phenotype associated with this type of brain malformation.

Abstract
Cerebro-oculo-facio-skeletal (COFS) syndrome is a recessively inherited rapidly progressive neurologic disorder leading to brain atrophy, with calcifications, cataracts, microcornea, optic atrophy, progressive joint contractures, and growth failure. Cockayne syndrome (CS) is a recessively inherited neurodegenerative disorder characterized by low to normal birth weight, growth failure, brain dysmyelination with calcium deposits, cutaneous photosensitivity, pigmentary retinopathy and/or cataracts, and sensorineural hearing loss. Cultured CS cells are hypersensitive to UV radiation, because of impaired nucleotide-excision repair (NER) of UV-induced damage in actively transcribed DNA, whereas global genome NER is unaffected. The abnormalities in CS are caused by mutated CSA or CSB genes. Another class of patients with CS symptoms have mutations in the XPB, XPD, or XPG genes, which result in UV hypersensitivity as well as defective global NER; such patients may concurrently have clinical features of another NER syndrome, xeroderma pigmentosum (XP). Clinically observed similarities between COFS syndrome and CS have been followed by discoveries of cases of COFS syndrome that are associated with mutations in the XPG and CSB genes. Here we report the first involvement of the XPD gene in a new case of UV-sensitive COFS syndrome, with heterozygous substitutions-a R616W null mutation (previously seen in patients in XP complementation group D) and a unique D681N mutation-demonstrating that a third gene can be involved in COFS syndrome. We propose that COFS syndrome be included within the already known spectrum of NER disorders: XP, CS, and trichothiodystrophy. We predict that future patients with COFS syndrome will be found to have mutations in the CSA or XPB genes, and we document successful use of DNA repair for prenatal diagnosis in triplet and singleton pregnancies at risk for COFS syndrome. This result strongly underlines the need for screening of patients with COFS syndrome, for either UV sensitivity or DNA-repair abnormalities.

Abstract
The Pena-Shokeir phenotype represents an autosomal recessive syndrome characterized by neurogenic arthrogryposis, facial anomalies and pulmonary hypoplasia. Prenatal diagnosis of this disease has been reported prospectively and in cases with positive family history. We describe here a patient who has had three consecutive pregnancies affected by the Pena-Shokeir syndrome. In these pregnancies, the onset of the arthrogryposis varied between the 12th and the 18th week of gestation. Therefore, the possibility of a variable chronological development of the main diagnostic feature of the syndrome, arthrogryposis, has to be taken into proper consideration while counseling families with a positive history for the Pena-Shokeir phenotype.

Abstract
Cerebro-oculo-facio-skeletal (COFS) syndrome is a rapidly progressive neurological disorder leading to brain atrophy with calcification, cataracts, microcornea, optic atrophy, progressive joint contractures, and growth failure. Cockayne syndrome (CS) is a recessively inherited neurodegenerative disorder characterized by low-to-normal birth weight; growth failure; brain dysmyelination with calcium deposits; cutaneous photosensitivity; pigmentary retinopathy, cataracts, or both; and sensorineural hearing loss. CS cells are hypersensitive to UV radiation because of impaired nucleotide excision repair of UV radiation-induced damage in actively transcribed DNA. The abnormalities in CS are associated with mutations in the CSA or CSB genes. In this report, we present evidence that two probands related to the Manitoba Aboriginal population group within which COFS syndrome was originally reported have cellular phenotypes indistinguishable from those in CS cells. The identical mutation was detected in the CSB gene from both children with COFS syndrome and in both parents of one of the patients. This mutation was also detected in three other patients with COFS syndrome from the Manitoba Aboriginal population group. These results suggest that CS and COFS syndrome share a common pathogenesis.

Abstract
A knowledge of those syndromes associated with congenital cataract is essential for the paediatric ophthalmologist, as congenital cataracts are manifest in a large number of syndromes. It is important to have the correct diagnosis in such cases, not only for genetic and prognostic information, but also in order to help the parents to understand their child's condition. This paper describes the more common syndromes seen in association with congenital cataract, and emphasises the importance of looking at the whole child and family. We aim to provide a practical clinical guide to the diagnosis of hereditary and non-hereditary syndromes associated with congenital cataract.

Abstract
Restrictive dermopathy (RD) is a lethal autosomal recessive genodermatosis (MIM No. 275210) in which tautness of the skin causes fetal akinesia or hypokinesia deformation sequence (FADS). Polyhydramnios with reduced fetal movements is followed by premature delivery at around 31 weeks gestation. Manifestations include a tightly adherent, thin, translucent skin with prominent vessels, typical facial changes, generalized joint contractures, enlarged fontanelles, dysplasia of clavicles, respiratory insufficiency, and an enlarged placenta with short umbilical cord. Histologic abnormalities of the skin include thin dermis with paucity and hypoplasia of the appendages and abnormally arranged collagen bundles. Elastic fibers are nearly missing. The subcutaneous fat is slightly increased. These skin findings usually appear after 22 or 24 weeks of gestation, which is why prenatal diagnosis with skin biopsy may fail. This disease is easily differentiated from other congenital FADS, such as Pena-Shokeir syndrome, COFS syndrome, Parana hard-skin syndrome, etc. We report on an affected boy of consanguineous parents and 30 previous cases are reviewed.

Abstract
Lenz microphthalmia syndrome was first described by Lenz et al in 1955. The cardinal features of the syndrome are microphthalmia or anophthalmos, narrow shoulders, other skeletal anomalies, and dental and urogenital malformations. Here we present a case of Lenz microphthalmia syndrome who shows the typical characteristics and, additionally, dysgenesis of the corpus callosum associated with dilatation of the lateral ventricles. The patient, a 13 year old male, was referred to our hospital by a dental hospital for genetic counselling. On physical examination, height, weight, and head circumference were below the 3rd centile and he had brachymicrocephaly, a preauricular tag, microphthalmia, missing teeth, narrow shoulders, long, proximally placed thumbs, hypospadias, cryptorchidism, and a normal IQ. Ophthalmological examination showed microcornea, sclerocornea, absence of the pupil, no vision in the left eye and decreased vision and a small pupil in the right eye in addition to his bilateral microphthalmia. Cranial MRI showed dilatation of the lateral ventricles and dysgenesis of the corpus callosum.

Abstract
An autopsy case is described of an infant with cerebro-oculo-facio-skeletal (COFS) (Pena-Shokeir II) syndrome who died of pneumonia at the age of 5 months, and the pathology of the CNS in this case and the cases in literature were reviewed. Neuropathological examination revealed a partial defect of the corpus callosum, lobulation of the caudate nucleus and putamen, polymicrogyria in the parietal lobes and neuronal heterotopia in the cerebral and cerebellar white matter. The migration disorders suggest that the onset starts in the early fetal period.

Abstract
We report on an Egyptian girl with phenotypic abnormalities of cerebro-oculofacio-skeletal syndrome. She had microcephaly, bilateral congenital cataract, nystagmus, long ear pinnae, camptodactyly, prominent heels, coxa valga, kyphosis and flexure contracture of the elbows and knees. CT scan showed bilateral symmetrical intracranial calcifications. In addition, she had an apparently balanced translocation: 46,XX,t(1;16)(q23;q13) in all cells transmitted from a phenotypically normal mother with a similar balanced translocation mosaicism. We suggest that genes for COFS syndrome could be located on chromosome 1q23 or 16q13. We recommend chromosomal analysis and DNA studies in cases with COFS manifestations.

Abstract
X-linked mental retardation (XLMR) is genetically heterogeneous and clinically variable. We describe a new XLMR syndrome of severe mental retardation and multiple congenital anomalies. Two sisters have (with 3 different partners) 3 severely handicapped sons. In 2 cases, oligohydramnios and intrauterine growth retardation were noted. Common anomalies included a square-shaped face, high and broad forehead, frontal bossing, downward slant of palpebral fissures, hypertelorism, epicanthic folds, long philtrum, thin upper lip, and apparently low-set ears. One boy has bilateral microphthalmos and sclerocornea, and his cousin has atrophy of the optic nerve. All 3 patients are blind and have profound statomotor and mental retardation, seizures, and a grossly abnormal electroencephalographic pattern. Additional findings are short stature, delayed bone maturation, hydronephrosis, vesicorenal reflux, cryptorchidism, clinodactyly of the 5th fingers, and transverse palmar creases. The karyotype is normal (46,XY). Segregation analysis showed perfect coinheritance between the clinical phenotype and alleles at several loci in Xp22.3, whereas recombinants were identified with marker loci from Xp22.2-qter. Analysis of multiple informative meioses suggests that the disease locus maps in Xp22.3 distal to DXS16.

Abstract
In an infant with clinical features of Pena-Shokeir I syndrome, who survived for 182 days, neuropathologic examination revealed little myelination in peripheral nerves with group atrophy of muscle fibers, dysplasia of inferior olivary and dentate nuclei, and leptomeningeal heterotopia. Congenital peripheral neuropathy associated with minor brain anomalies is characteristic in this patient, and may cause absence of fetal movements leading to ankylosis of multiple joints, absence of breathing in association with pulmonary hypoplasia, absence of swallowing causing polyhydramnios, and absence of movements of facial muscles causing craniofacial anomalies.

Abstract
We report on 8 patients from two families with Alpers syndrome. The onset in one family was prenatal and in the 4 patients who were examined, severe microcephaly, intrauterine growth retardation, and typical manifestations of fetal akinesia, including retrognathia, joint limitations, and chest deformity were found. The second family presented with an early infantile form. All the affected offspring had micrognathia and one had findings of fetal akinesia, comparable to those seen in the other family. Microcephaly was mild at birth and progressed with age. Refractory neonatal convulsions, swallowing difficulties, and pneumonia complicated the clinical course of patients in both families, and all the patients died before age 20 months. Results of comprehensive biochemical and metabolic studies in both families were normal and the diagnosis was supported by demonstration of extensive progressive brain atrophy on CT and typical histological findings. Patients without a detectable defect in energy metabolism and normal liver histology comprise a distinct subset of Alpers syndrome. Until the metabolic defect(s) is defined, we suggest naming the acute neonatal form of this subset of Alpers syndrome "type 1."

Abstract
Cerebro-oculo-facial-skeletal (COFS) syndrome is a rare, autosomal recessive syndrome characterized by microcephaly, microphthalmia and/or cataracts, neurogenic arthrogryposis, and multiple congenital anomalies. A term female infant with COFS syndrome who developed infantile spasms at the age of 3 months is reported. The patient had a good response to intramuscular ACTH with disappearance of infantile spasms and resolution of the hypsarrhythmic pattern on electroencephalography succeeded by a slow, synchronous pattern. Modified hypsarrhythmia returned after ACTH therapy was discontinued. Infantile spasms have not previously been reported in association with COFS syndrome and are a potentially treatable aspect of the disease. This patient may add to the clinical spectrum of COFS syndrome or may have a variant.

Abstract
Pena-Shokeir phenotype is a unique pattern of lethal multiple congenital anomalies with variable expression. The history of a family in which two sibs conform to Pena-Shokeir phenotype is detailed and substantiates the criteria for definition of the phenotype. The addition of a peculiar ultrasound presentation in the antenatal period may indicate the condition.

Abstract
We have studied a boy with acrocallosal syndrome and hypogenitalism. He was the offspring of double first cousins. He had unusual facial appearance, postaxial polydactyly with unilateral soft tissue syndactyly of fingers, mental retardation, and absence of corpus callosum. Findings in the present case were compared with those of previously reported cases. Other syndromes associated with agenesis of the corpus callosum must be differentiated. The main differences between the acrocallosal syndrome and the Greig syndrome are outlined with particular emphasis on digital anomalies. The acrocallosal syndrome is an autosomal recessive trait with variable expressivity. Hypogenitalism may be a presenting feature. Positive consanguinity provides further evidence for autosomal recessive inheritance.

Abstract
Two patients with early onset Cockayne's syndrome are presented. In each case there was a striking failure of growth and developmental deterioration around six months of age. It has been suggested that early onset Cockayne's syndrome is a syndrome distinct from Cockayne's syndrome, but when the first patient died aged two years 10 months, examination of the brain showed a leucodystrohy with 'tigroid' demyelination similar to that reported in later onset cases of Cockayne's syndrome. Studies of the effects of UV irradiation on cultured fibroblasts from patients showed similar levels of inhibition of RNA synthesis to those seen in a control with Cockayne's syndrome. This evidence suggests it is appropriate to classify early onset Cockayne's syndrome with Cockayne's syndrome. Since there is a phenotypic overlap between early onset Cockayne's syndrome and COFS syndrome, they may both be classified within the same diagnostic group, but as yet no cellular studies with UV irradiation have been performed in COFS syndrome.
