Invitae RCV001343203 SCV001537167 likely pathogenic Smith-Lemli-Opitz syndrome 2023-03-10 criteria provided, single submitter clinical testing In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt DHCR7 protein function. ClinVar contains an entry for this variant (Variation ID: 1039683). This missense change has been observed in individual(s) with clinical features of Smith-Lemli-Opitz syndrome (Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 261 of the DHCR7 protein (p.Glu261Gly).
GeneDx RCV001751671 SCV001994894 uncertain significance not provided 2019-09-04 criteria provided, single submitter clinical testing Not observed in large population cohorts (Lek et al., 2016); The majority of missense variants in this gene are considered pathogenic [(Stenson et al., 2014; other references)]; In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; Has not been previously published as pathogenic or benign to our knowledge
