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 submitter	clinical testing	Invitae	Jan 22, 2024	This sequence change creates a premature translational stop signal (p.Arg1030*) in the ABCC6 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ABCC6 are known to be pathogenic (PMID: 11536079, 17617515). This variant is present in population databases (rs72653705, gnomAD 0.003%). This premature translational stop signal has been observed in individual(s) with clinical features of pseudoxanthoma elasticum (PMID: 11536079, 15459974). ClinVar contains an entry for this variant (Variation ID: 433300). For these reasons, this variant has been classified as Pathogenic. -
