Genes affected

NSDHL (HGNC:13398): (NAD(P) dependent steroid dehydrogenase-like) 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]

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 436070). This variant has not been reported in the literature in individuals affected with NSDHL-related conditions. This variant is present in population databases (rs782181497, gnomAD 0.006%), including at least one homozygous and/or hemizygous individual. This sequence change replaces tyrosine, which is neutral and polar, with histidine, which is basic and polar, at codon 302 of the NSDHL protein (p.Tyr302His). -
