This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 143 of the CYP11B1 protein (p.Arg143Trp). This variant is present in population databases (rs140336749, gnomAD 0.1%). This missense change has been observed in individuals with clinical features of adrenal hyperplasia (PMID: 23940125, 24022297, 26053152). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 56831). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on CYP11B1 protein function. Experimental studies have shown that this missense change affects CYP11B1 function (PMID: 23940125). For these reasons, this variant has been classified as Pathogenic.
