Description

Variant summary: DHCR7 c.1168C>T (p.His390Tyr) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 8.1e-05 in 246406 control chromosomes (gnomAD). This frequency is lower than the estimated maximum expected for a pathogenic variant in DHCR7 causing Smith-Lemli-Opitz Syndrome (0.0043), allowing no conclusion about variant significance. To our knowledge, no occurrence of c.1168C>T in individuals affected with Smith-Lemli-Opitz Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014, and all classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance.
