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]

Likely pathogenic, criteria provided, single submitterclinical testingGeneDxMar 23, 2018The c.2861_2866delTCCTCT variant has been published previously in three patients who were also heterozygous for the R518Q variant in the ABCC6 gene (Hosen et al., 2015). It was not observed in approximately 6,400 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. This deletion causes the loss of two conserved residues, Phenylalanine 954 and Leucine 955, in a conserved transmembrane domain. In summary, the c.2861_2866delTCCTCT variant is a strong candidate for a disease-causing variant. -
Likely pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJul 22, 2023In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. ClinVar contains an entry for this variant (Variation ID: 265019). This variant has been observed in individual(s) with pseudoxanthoma elasticum or generalized arterial calcification of infancy (PMID: 25264593, 33005041). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is present in population databases (rs767359198, gnomAD 0.02%). This variant, c.2861_2866del, results in the deletion of 2 amino acid(s) of the ABCC6 protein (p.Phe954_Leu955del), but otherwise preserves the integrity of the reading frame. -
