Description

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 53 of the ACADM protein (p.Arg53Cys). This variant is present in population databases (rs398123072, gnomAD 0.02%). This missense change has been observed in individual(s) with MCAD deficiency (PMID: 8102510, 15832312, 16737882, 20434380, 22796001, 24623196). This variant is also known as R28C. ClinVar contains an entry for this variant (Variation ID: 92258). 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 ACADM protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects ACADM function (PMID: 8102510, 26947917). For these reasons, this variant has been classified as Pathogenic.
