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]

ABCC6-related disorder Pathogenic:1
Pathogenic, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesJun 13, 2024The ABCC6 c.105delA variant is predicted to result in a frameshift and premature protein termination (p.Ala35Alafs*46). This variant has been reported in the compound heterozygous state in individuals with pseudoxanthoma elasticum (Miksch et al. 2005. PubMed ID: 16086317; Table S1, Saeidian et al. 2021. PubMed ID: 34906475). This variant is reported in 1 allele in individuals of African descent in gnomAD. Frameshift variants in ABCC6 are expected to be pathogenic. This variant is interpreted as pathogenic. -
