Invitae RCV001390621 SCV001592411 pathogenic not provided 2023-12-30 criteria provided, single submitter clinical testing This sequence change replaces leucine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 260 of the STAR protein (p.Leu260Pro). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This missense change has been observed in individual(s) with congenital adrenal hyperplasia (PMID: 15985476, 20444910). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 553482). 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 STAR protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects STAR function (PMID: 15985476, 20444910). For these reasons, this variant has been classified as Pathogenic.
