Labcorp Genetics (formerly Invitae), Labcorp RCV000809884 SCV000950065 pathogenic not provided 2023-12-30 criteria provided, single submitter clinical testing This sequence change replaces histidine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 373 of the CYP17A1 protein (p.His373Leu). This variant is present in population databases (rs760695410, gnomAD 0.02%). This missense change has been observed in individual(s) with congenital adrenal hyperplasia (PMID: 8245018, 10877510, 11549876, 12706306, 24140098). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 654004). 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 CYP17A1 protein function with a positive predictive value of 95%. Experimental studies have shown that this missense change affects CYP17A1 function (PMID: 8245018). For these reasons, this variant has been classified as Pathogenic.
