New York Genome Center RCV001542322 SCV001761008 uncertain significance Desmosterolosis 2020-07-03 criteria provided, single submitter clinical testing The homozygous c.286G>C (p.Gly96Arg) variant identified in the DHCR24 gene substitutes a well conserved Glycine for Arginine at amino acid 96/517 (exon 2/9). This variant is absent from gnomAD suggesting it is not a common benign variant in the populations represented in that database. In silico algorithms predict this variant to be Deleterious (Provean; score: -6.19) and Damaging (SIFT; score:0.026) to the function of the canonical transcript. This variant is absent from ClinVar and to our current knowledge has not been reported in affected individuals in the literature. The p.Gly96 residue is within the FAD-binding PCMH-type domain of DHCR24 (UniProtKB:Q15392), and while the p.Gly96Arg variant has not been described in affected individuals in the literature, a variant within the same domain and two amino acids upstream (p.Arg94His) has been reported in an affected individual in the literature [PMID:21671375]. The homozygous c.286G>C (p.Gly96Arg) variant identified in the DHCR24 gene is reported as a Variant of Uncertain Significance.
