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]

The ABCC6 c.1132C>T variant is predicted to result in premature protein termination (p.Gln378*). This variant has been reported in individuals with pseudoxanthoma elasticum (PXE) (Cai et al. 2001. PubMed ID: 11692167; Katagiri et al. 2017. PubMed ID: 28912966; Mitre et al. 2018. PubMed ID: 30537162; Boraldi et al. 2021. PubMed ID: 34205333; Jin et al. 2021. PubMed ID: 34440381). However, this variant also localizes to the ABCC6P1 pseudogene and may be transferred to the native ABCC6 gene through gene conversion in some individuals (Cai et al. 2001. PubMed ID: 11692167; Casola. 2012. PubMed ID: 22090377; Katagiri et al. 2017. PubMed ID: 28912966).This variant is reported in 0.040% of alleles in individuals of East Asian descent in gnomAD. However, this variant falls within a highly paralogous region. Allele frequency data should be interpreted with caution. Nonsense variants in ABCC6 are expected to be pathogenic. This variant is interpreted as pathogenic. -
