Entrez Gene Summary for NSDHL Gene

  • The protein encoded by this gene is localized in the endoplasmic reticulum and is involved in cholesterol biosynthesis. Mutations in this gene are associated with CHILD syndrome, which is a X-linked dominant disorder of lipid metabolism with disturbed cholesterol biosynthesis, and typically lethal in males. Alternatively spliced transcript variants with differing 5' UTR have been found for this gene. [provided by RefSeq, Jul 2008]

  • Congenital hemidysplasia with ichthyosiform erythroderma and limb defects (CHILD) [MIM:308050]: An X-linked dominant disorder of lipid metabolism with disturbed cholesterol biosynthesis, which typically results in male lethality. Clinically, it is characterized by congenital, unilateral, ichthyosisform erythroderma with striking lateralization, sharp midline demarcation, and ipsilateral limb defects and hypoplasia of the body. Limbs defects range from hypoplasia of digits or ribs to complete amelia, often including scoliosis. {ECO:0000269 PubMed:10710235, ECO:0000269 PubMed:11907515}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • CK syndrome (CKS) [MIM:300831]: A disorder characterized by mild to severe cognitive impairment, seizures, microcephaly, cerebral cortical malformations, dysmorphic facial features, and thin body habitus. {ECO:0000269 PubMed:21129721}. Note=The disease is caused by mutations affecting the gene represented in this entry.
