A Consensus Conference utilizing available literature and expert opinion sponsored by the American College of Medical Genetics in October 1995 evaluated the rational approach to the individual with mental retardation. Although no uniform protocol replaces individual clinician judgement, the consensus recommendations were as follows: 1. The individual with(More)
Mutations in the GLI3 zinc-finger transcription factor gene cause Greig cephalopolysyndactyly syndrome (GCPS) and Pallister-Hall syndrome (PHS), which are variable but distinct clinical entities. We hypothesized that GLI3 mutations that predict a truncated functional repressor protein cause PHS and that functional haploinsufficiency of GLI3 causes GCPS. To(More)
Kabuki syndrome is a multiple congenital anomaly/mental retardation syndrome. This study of Kabuki syndrome had two objectives. The first was to further describe the syndrome features. In order to do so, clinical geneticists were asked to submit cases-providing clinical photographs and completing a phenotype questionnaire for individuals in whom they felt(More)
There is an assumption of parsimony with regard to the number of chromosomes involved in rearrangements and to the number of breaks within those chromosomes. Highly complex chromosome rearrangements are thought to be relatively rare, with the risk for phenotypic abnormalities increasing as the number of chromosomes and chromosomal breaks involved in the(More)
Myotubular myopathy is a subtype of centronuclear myopathy with X-linked inheritance and distinctive clinical and pathologic features. Most boys with myotubular myopathy have MTM1 mutations. In remaining individuals, it is not clear if disease is due to an undetected alteration in MTM1 or mutation of another gene. We describe a boy with myotubular myopathy(More)
Analysis of the literature yielded 42 examples of the combination of sternal non-union and supraumbilical raphé without evidence of sex predilection. However, among an additional 31 cases in which the triad included facial hemangioma, there was almost exclusive female occurrence. Another condition involves extensive unilateral hemangioma of the face,(More)
OBJECTIVE To describe an infant with early excessive weight gain as the principle manifestation of pseudohypoparathyroidism (PHP) type 1a and Albright hereditary osteodystrophy (AHO). METHODS We describe the clinical and laboratory findings in an infant with early excessive weight gain without evidence of hyperphagia and review relevant literature. (More)
OBJECTIVE To describe the clinical outcome of fetuses with the prenatal sonographic diagnosis of isolated micrognathia. METHODS A retrospective review of fetuses and infants with the prenatal diagnosis of isolated micrognathia for April 1990 to August 2001 was undertaken. Isolated micrognathia was considered if no other anatomic, growth, or amniotic fluid(More)
Jacobsen syndrome is an uncommon but well-known contiguous gene syndrome caused by partial deletion involving the long arm of chromosome 11. Most common features include: psychomotor impairment, facial dysmorphism, and thrombocytopenia. Cleft palate has been rarely reported. A case of Jacobsen syndrome confirmed by cytogenomic analysis is presented with(More)
