Cornelia de Lange syndrome (CdLS; OMIM 122470) is a dominantly inherited multisystem developmental disorder characterized by growth and cognitive retardation; abnormalities of the upper limbs; gastroesophageal dysfunction; cardiac, ophthalmologic and genitourinary anomalies; hirsutism; and characteristic facial features. Genital anomalies, pyloric stenosis,(More)
DNA sequence and annotation of the entire human chromosome 7, encompassing nearly 158 million nucleotides of DNA and 1917 gene structures, are presented. To generate a higher order description, additional structural features such as imprinted genes, fragile sites, and segmental duplications were integrated at the level of the DNA sequence with medical(More)
OBJECTIVE The authors examined the relationship between cholesterol metabolism and suicidality in carriers of Smith-Lemli-Opitz syndrome and their families. This population has a partial deficiency in 7-dehydrocholesterol reductase (DHCR7), the enzyme that catalyzes the last step in cholesterol biosynthesis. METHOD Suicidal behavior, depression, misuse of(More)
PURPOSE The purpose of the current study was to assess the penetrance of NRXN1 deletions. METHODS We compared the prevalence and genomic extent of NRXN1 deletions identified among 19,263 clinically referred cases to that of 15,264 controls. The burden of additional clinically relevant copy-number variations (CNVs) was used as a proxy to estimate the(More)
