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	Labcorp Genetics (formerly Invitae), Labcorp	Jan 14, 2024	This sequence change creates a premature translational stop signal (p.Lys1394Asnfs*9) 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 (rs67791546, gnomAD 0.01%). This premature translational stop signal has been observed in individuals with pseudoxanthoma elasticum (PMID: 12673275). ClinVar contains an entry for this variant (Variation ID: 433351). For these reasons, this variant has been classified as Pathogenic. -
