Labcorp Genetics (formerly Invitae), Labcorp RCV001918453 SCV002184999 uncertain significance 3-methylcrotonyl-CoA carboxylase 1 deficiency 2021-05-06 criteria provided, single submitter clinical testing 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 MCCC1 protein function. This variant has been observed in individual(s) with 3MCC deficiency (Invitae). This variant is not present in population databases (ExAC no frequency). This sequence change replaces histidine with arginine at codon 88 of the MCCC1 protein (p.His88Arg). The histidine residue is highly conserved and there is a small physicochemical difference between histidine and arginine. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
