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 c.3971G>A;p.Trp1324* variant creates a premature translational stop signal in the ABCC6 gene. It is expected to result in an absent or disrupted protein product - PVS1. This sequence change has been observed in affected individual(s) and ClinVar contains an entry for this variant (ClinVar ID: 433339; PMID: 23572048) - PS4_supporting. The variant is present at low allele frequencies population databases (rs72653750 – gnomAD 0.00006575%; ABraOM 0.000854 frequency - https://abraom.ib.usp.br/) - PM2_supporting. In summary, the currently available evidence indicates that the variant is pathogenic. -

This sequence change creates a premature translational stop signal (p.Trp1324*) 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 not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with clinical features of pseudoxanthoma elasticum (PMID: 23572048). This variant is also known as W1324X. ClinVar contains an entry for this variant (Variation ID: 433339). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
