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]

Pathogenic:3

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 01, 2024	This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 1138 of the ABCC6 protein (p.Arg1138Gln). This variant is present in population databases (rs60791294, gnomAD 0.01%). This missense change has been observed in individuals with pseudoxanthoma elasticum (PMID: 10811882, 10835642, 15459974, 15752294). ClinVar contains an entry for this variant (Variation ID: 6561). 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%. Experimental studies have shown that this missense change affects ABCC6 function (PMID: 24352041). For these reasons, this variant has been classified as Pathogenic. -
