Genes affected

ABCC6 (HGNC:57): (ATP binding cassette subfamily C member 6) The protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). The encoded protein, a member of the MRP subfamily, is involved in multi-drug resistance. Mutations in this gene cause pseudoxanthoma elasticum. Alternatively spliced transcript variants that encode different proteins have been described for this gene. [provided by RefSeq, Jul 2008]

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 600 of the ABCC6 protein (p.Arg600Cys). This variant is present in population databases (rs72653777, gnomAD 0.03%). This missense change has been observed in individuals with pseudoxanthoma elasticum (PMID: 15459974, 20075945, 32873932). ClinVar contains an entry for this variant (Variation ID: 433243). 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 ABCC6 protein function with a positive predictive value of 95%. This variant disrupts the p.Arg600 amino acid residue in ABCC6. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 18513494). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -
