University Children's Hospital, University of Zurich RCV000235906 SCV000262803 pathogenic Methylmalonic aciduria due to methylmalonyl-CoA mutase deficiency criteria provided, single submitter clinical testing
Invitae RCV001853322 SCV002199631 pathogenic not provided 2022-11-29 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. 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 MUT protein function. ClinVar contains an entry for this variant (Variation ID: 222931). This missense change has been observed in individual(s) with methylmalonic aciduria (PMID: 27167370; Invitae). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 424 of the MUT protein (p.Pro424Leu).
