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]

ACMG classification

Classification made for transcript

Verdict is Pathogenic. Variant got 10 ACMG points.

PVS1

Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.04055851 fraction of the gene. Cryptic splice site detected, with MaxEntScore 5.3, offset of 1, new splice context is: cctctttgtgttccctcaAGtct. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.

PP5

Variant 16-16221832-C-T is Pathogenic according to our data. Variant chr16-16221832-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 433372.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr16-16221832-C-T is described in Lovd as [Pathogenic].
