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 methionine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 834 of the ABCC6 protein (p.Met834Thr). This variant is present in population databases (no rsID available, gnomAD 0.003%). This missense change has been observed in individual(s) with pseudoxanthoma elasticum (PMID: 25615550). ClinVar contains an entry for this variant (Variation ID: 433502). 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 not expected to disrupt ABCC6 protein function. Experimental studies have shown that this missense change affects ABCC6 function (PMID: 25615550). 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. -
