Abstract
Pathogenic variants in the LMNA gene cause a group of heterogeneous genetic disorders, called laminopathies. In particular, homozygous or compound heterozygous variants in LMNA have been associated with “mandibuloacral dysplasia type A” (MADA), an autosomal recessive disorder, characterized by mandibular hypoplasia, growth retardation mainly postnatal, pigmentary skin changes, progressive osteolysis of the distal phalanges and/or clavicles, and partial lipodystrophy. The detailed characteristics of this multisystemic disease have yet to be specified due to its rarity and the limited number of cases described. Here, we report three unrelated Egyptian patients with variable severity of MAD features. Next-generation sequencing using a gene panel revealed a homozygous c.1580G>A-p.Arg527His missense variant in LMNA exon 9 in an affected individual with a typical MADA phenotype. Another homozygous c.1580G>T-p.Arg527Leu variant affecting the same amino acid was identified in two additional patients, who both presented with severe manifestations very early in life. We combined our observations together with data from all MADA cases reported in the literature to get a clearer picture of the phenotypic variability in this disease. This work raises the number of reported MADA families, argues for the presence of the founder effect in Egypt, and strengthens genotype–phenotype correlations.

Abstract
CASE The phenomenon of acro-osteolysis often intrigues clinicians and patients alike, as it causes bone resorption. One such condition is Hajdu-Cheney syndrome. We report our experience in identifying and halting the active bone resorption in a patient and his father with 2-year follow-up results. CONCLUSION Management included identification of the NOTCH2 mutation and treatment with antiresorptive measures. In addition, genetic counseling and antenatal counseling are recommended to explain the risk of inheritance.

Abstract
BACKGROUND Mandibuloacral dysplasia (MAD) is a rare autosomal recessive disorder characterized by skeletal abnormalities such as hypoplasia of the mandible and clavicles and acro-osteolysis. Other features include cutaneous atrophy and lipodystrophy. Two genetic loci are known for MAD: lamin A/C (LMNA), encoding structural nuclear lamina proteins, and zinc metalloproteinase (ZMPSTE24), a membrane-bound endoprotease involved in post-translational proteolytic cleavage of carboxy terminal residues of prelamin A to form mature lamin A. METHODS Mutational analysis of ZMPSTE24 in an additional patient with MAD and determination of functional activity of mutant ZMPSTE24 in a yeast growth arrest pheromone diffusion (halo) assay. RESULTS We previously reported a Belgian woman with MAD who had ZMPSTE24 mutations and died of complications of chronic renal failure at the age of 27.5 years. We now report a 37-year-old Australian man with MAD who also had compound heterozygous mutations in the ZMPSTE24 gene, a null mutation, Phe361fsX379, and a missense mutation, Asn265Ser, which is partially active in the yeast complementation assay. He also developed end-stage renal disease and, despite receiving a cadaveric renal transplantation, died prematurely at the age of 37 years. Renal biopsies of both patients revealed focal segmental glomerulosclerosis, and the female patient had the collapsing variant. CONCLUSION These observations suggest focal segmental glomerulosclerosis as a phenotypic manifestation in patients with ZMPSTE24 deficiency.

Abstract
We report on a patient with blepharophimosis who after unsuccessful surgery developed progressive corneal vascularization. The patient had conductive hearing loss, acroosteolysis of the phalanges, arthropathy, loss of subcutaneous fat of the hands, feet and face, and oligospermia. He had had spontaneous pneumothorax four times. We have found no similar case reports in the literature and suggest that this is a new syndrome, which must be differentiated from hereditary mucoepithelial dysplasia, mandibuloacral dysplasia, keratitis-ichthyosis-deafness syndrome, Hajdu-Cheney syndrome, Penttinen syndrome, and mucopolysaccharidoses.

Abstract
The laminopathies are a diverse group of conditions caused by mutations in the LMNA gene (MIM*150330). LMNA encodes the nuclear envelope proteins lamin A and lamin C by utilization of an alternative splice site in exon 10. The human LMNA gene was identified in 1986 but it was another 13 years before it was found to be the causative gene for a disease, namely Emery Dreifuss muscular dystrophy. Since then, a further eight clearly defined phenotypes have been associated with LMNA mutations. The diversity of these phenotypes is striking with features such as premature ageing, axonal neuropathy, lipodystrophy and myopathy being seen. These phenotypes and the emerging genotype/phenotype correlations are the subject of this review.

Abstract
Mandibuloacral dysplasia (MAD) is a rare disorder. Only 35 patients, coming from 22 families, have been reported worldwide. We report on two Egyptian unrelated girls with MAD. The first patient presented at the age of 5 years with acral defect and partial alopecia. The second patient presented at the age of 17 years with progressive micrognathia and loss of subcutaneous fat from the limbs. Physical examination detected the craniofacial, skeletal and cutaneous changes characteristic of MAD. Both patients were short with progeroid facies and loss of subcutaneous fat from the extremities, which fits lipodystrophy type A pattern. Radiological examination revealed delayed closure of cranial sutures, hypoplastic mandible, hypoplastic clavicles, and acroosteolysis. Both patients had normal glucose tolerance, but had fasting and post-prandial hyperinsulinemia, suggestive of insulin resistance. One patient had elevated serum triglycerides and low normal cholesterol levels, while the other patient had normal levels. Serum leptin was normal in both patients. We review the literature on mandibuloacral dysplasia and discuss the differential diagnosis.

Abstract
Mandibuloacral dysplasia (MAD; OMIM 248370) is a rare, genetically and phenotypically heterogeneous, autosomal recessive disorder characterized by skeletal abnormalities including hypoplasia of the mandible and clavicles, acro-osteolysis, cutaneous atrophy and lipodystrophy. A homozygous missense mutation, Arg527His, in the LMNA gene which encodes nuclear lamina proteins lamins A and C has been reported in patients with MAD and partial lipodystrophy. We studied four patients with MAD who had no mutations in the LMNA gene. We now show compound heterozygous mutations, Phe361fsX379 and Trp340Arg, in the zinc metalloproteinase (ZMPSTE24) gene in one of the four patients who had severe MAD associated with progeroid appearance and generalized lipodystrophy. ZMPSTE24 is involved in post-translational proteolytic cleavage of carboxy terminal residues of farnesylated prelamin A in two steps to form mature lamin A. Deficiency of Zmpste24 in mice causes accumulation of prelamin A and phenotypic features similar to MAD. The yeast homolog, Ste24, has a parallel role in processing of prenylated mating pheromone a-factor. Since human ZMPSTE24 can also process a-factor when expressed in yeast, we assessed the functional significance of the two ZMPSTE24 mutations in the yeast to complement the mating defect of the haploid MATa yeast lacking STE24 and Ras-converting enzyme 1 (RCE1; another prenylprotein-specific endoprotease) genes. The ZMPSTE24 mutant construct, Phe361fsX379, was inactive in complementing the yeast a-factor but the mutant, Trp340Arg, was partially active compared to the wild type ZMPSTE24 construct. We conclude that mutations in ZMPSTE24 may cause MAD by affecting prelamin A processing.

Abstract
Hadju-Cheney syndrome is characterized by short stature, distinctive facies, and a slowly progressive skeletal dysplasia including acro-osteolysis. Autosomal dominant inheritance is typical, but the genetic defect and molecular pathogenesis of the syndrome are unknown. Osteoporosis with atraumatic fracture is a frequent finding, and previous studies have documented biochemical and morphometric evidence of high bone turnover. Here, we report the clinical details and response to therapy with bisphosphonates in two patients (mother and son) with Hadju-Cheney syndrome and postulate that osteoclast-mediated bone resorption is important in the generalized osteoporosis commonly associated with this condition.

Abstract
We report the combination of hemifacial microsomia, external auditory canal atresia, deafness and acro-osteolysis in several members of a highly consanguineous Asian family. In addition Mullerian anomalies have been found in two female members of the family. The external auditory canal stenosis and Mullerian anomalies in this family are similar to those reported by Winter et al. [(1968) J Pediatr 72 : 88-93] and overlap with those found in Goldenhar syndrome and Mullerian duct/renal aplasia/cervicothoracic somite dysplasia (MURCS), CHARGE and VATER associations. However, to the authors' knowledge, acro-osteolysis has not been reported in patients with any of these conditions. Overall, the findings in this family appear to be unique and the presence of consanguinity suggests an autosomal recessive condition with variable expression.
