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, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 03, 2023This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 518 of the ABCC6 protein (p.Arg518Gln). This variant is present in population databases (rs72653772, gnomAD 0.01%). This missense change has been observed in individuals with pseudoxanthoma elasticum (PMID: 15459974, 20075945). ClinVar contains an entry for this variant (Variation ID: 265018). 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. For these reasons, this variant has been classified as Pathogenic. -
Pathogenic, criteria provided, single submitterclinical testingGeneDxFeb 22, 2024In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 34906475, 27057999, 30879837, 12384774, 15086542, 25264593, 25595835, 28102862, 31589614, 34205333, 35261845, 36317459, 32873932, 38112957, 15459974, 37259549, 20075945, 23485117) -

Pathogenic, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesSep 10, 2024The ABCC6 c.1553G>A variant is predicted to result in the amino acid substitution p.Arg518Gln. This variant has been reported as a founder variant in individuals of North African descent with autosomal recessive pseudoxanthoma elasticum (Legrand et al. 2017. PubMed ID: 28102862; Chassaing et al. 2004. PubMed ID: 15086542; Le Saux et al 2002. PubMed ID: 12384774; Ramsay et al. 2009. PubMed ID: 19339160).
