Abstract
Described for the first time in 1971, Schimke immuno-osseous dysplasia (SIOD) is an autosomal-recessive multisystem disorder that is caused by bi-allelic mutations of SMARCAL1, which encodes a DNA annealing helicase. To define better the dental anomalies of SIOD, we reviewed the records from SIOD patients with identified bi-allelic SMARCAL1 mutations, and we found that 66.0% had microdontia, hypodontia, or malformed deciduous and permanent molars. Immunohistochemical analyses showed expression of SMARCAL1 in all developing teeth, raising the possibility that the malformations are cell-autonomous consequences of SMARCAL1 deficiency. We also found that stimulation of cultured skin fibroblasts from SIOD patients with the tooth morphogens WNT3A, BMP4, and TGFβ1 identified altered transcriptional responses, raising the hypothesis that the dental malformations arise in part from altered responses to developmental morphogens. To the best of our knowledge, this is the first systematic study of the dental anomalies associated with SIOD.

Abstract
We report the unique CNS findings in a patient with a proximal chromosome 14q interstitial deletion. Conventional MR imaging allowed the clear delineation of agenesis of the corpus callosum, SOD, and diffuse lissencephaly. DTI tractography played a significant role in the evaluation of the proximal 14q deletion-associated abnormalities, delineating the extent of the dysmorphic connections of the Probst bundles and clarifying that apparent areas of heterotopias were the corticospinal tracts.

Abstract
Attention to a careful diagnostic work-up should be given to patients with postaxial polydactyly or apparently isolated hypothalamic hamartomas. Early recognition of the condition is critical for management, particularly for anticipating and preventing endocrine emergencies. Conservative management of the hypothalamic hamartoma should be stressed. Finally, detailed genetic counseling should be provided to the family regarding autosomal-dominant inheritance as well as the wide range of interfamilial and intrafamilial variability.

Abstract
Pallister-Hall syndrome (PHS, M146510) was first described in 1980 in six newborns. It is a pleiotropic disorder of human development that comprises hypothalamic hamartoma, central polydactyly, and other malformations. This disorder is inherited as an autosomal dominant trait and has been mapped to 7p13 (S. Kang et al. Autosomal dominant Pallister-Hall syndrome maps to 7p13. Am. J. Hum. Genet. 59, A81 (1996)), co-localizing the PHS locus and the GLI3 zinc finger transcription factor gene. Large deletions or translocations resulting in haploinsufficiency of the GLI3 gene have been associated with Greig cephalopolysyndactyly syndrome (GCPS; M175700) although no mutations have been identified in GCPS patients with normal karyotypes. Both PHS and GCPS have polysyndactyly, abnormal craniofacial features and are inherited in an autosomal dominant pattern, but they are clinically distinct. The polydactyly of GCPS is commonly preaxial and that of PHS is typically central or postaxial. No reported cases of GCPS have hypothalamic hamartoma and PHS does not cause hypertelorism or broadening of the nasal root or forehead. The co-localization of the loci for PHS and GCPS led us to investigate GLI3 as a candidate gene for PHS. Herein we report two PHS families with frameshift mutations in GLI3 that are 3' of the zinc finger-encoding domains, including one family with a de novo mutation. These data implicate mutations in GLI3 as the cause of autosomal dominant PHS, and suggest that frameshift mutations of the GLI3 transcription factor gene can alter the development of multiple organ systems in vertebrates.

Abstract
Thrombocytopenia with absent radius (TAR) syndrome is infrequently (7%) associated with mental retardation. In those cases, the mental deficiency is presumed to be a consequence of intracranial hemorrhage due to the thrombocytopenia. We report on 2 infants with TAR syndrome. One had developmental delay with evidence of cerebral dysgenesis by magnetic resonance imaging (MRI). Such findings have not been noted in the literature, but may not have been investigated in most cases. The other infant with TAR syndrome, who has had normal psychomotor development, has a normal brain on MRI scan. Detailed neuroimaging studies, preferably MRI, should be considered in the evaluation of patients with TAR syndrome, especially when there are documented signs of developmental delay, with or without a history of intracranial hemorrhage.

Abstract
We report the brain magnetic resonance imaging findings in 4 patients with the Opitz BBB/G syndrome. The scans were assessed by subjective interpretation and computerized image analysis. Findings noted in 3 of the 4 patients include hypoplasia or agenesis of the corpus callosum (3 patients), cerebellar vermal hypoplasia (2 patients), cortical atrophy and ventriculomegaly (3 patients), macro cisterna magna (3 patients), and a wide cavum septum pellucidum (1 patient). One patient had a normal scan. The demonstration of a wide cavum septum pellucidum extends the spectrum of midline brain anomalies (ventral induction defects) reported in this condition. This study along with other recent reports suggests that midline brain anomalies may be frequent findings in Opitz syndrome.

Abstract
The propositus and a subsequently born sister presented with multiple congenital anomalies. Chromosome analyses were performed initially on peripheral blood lymphocytes from the propositus and his parents: the propositus was found to have a deletion of chromosome 14 (q32.11- greater than qter); the parents' chromosomes were normal. When the sister of the propositus was born, she was determined to have a duplication of an equivalent segment of 14qter. Chromosome studies on the parents' fibroblasts demonstrated no structural abnormality or mosaicism. The parents have an older, phenotypically normal, healthy daughter, which supports mosaicism for intragonadal t(14;14)(q32.11;q32.33) in one parent. Chromosome polymorphism comparisons show that the normal number 14 chromosome in the propositus and his sister was inherited from the mother, thus indicating paternal testicular mosaicism. Clinical findings are compared to those of other reported cases of deletion 14q and duplication 14q.

Abstract
A detailed genetic and physical map of human complement factor I (IF) using somatic cell hybrids, in situ hybridization, and genetic linkage is reported. The gene has been localized to band 4q25. The order GC-INP10-ADH3-EGF-IF-IL2-MNS is proposed for genes on 4q on the basis of genetic and physical mapping techniques. A BclI polymorphism found with the IF probe demonstrated a maternal origin for a de novo deletion of chromosome 4 that was used in physically mapping the gene. The genetic and physical distances around band 4q24 suggest that 1 cM is approximately 1.2 million bp of DNA. This work provides a useful addition to the map of 4q.

Abstract
We report 3 pairs of monozygotic (MZ) twins, one twin showing typical Wiedemann-Beckwith syndrome (WBS) with minimal or no expression of the condition in the co-twin. These cases are documented, and three previously reported MZ twin pairs are reviewed. Phenotypic concordance for this syndrome in MZ twin pairs has not been reported. Many cases of familial occurrence have been published and different modes of inheritance have been postulated. Based on the twin-twin variability seen in our patients, it seems the most likely mechanism of inheritance is an autosomal dominant mutation with environmental modification of expressivity, or reduced phenotrance.
