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

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BP6: Variant 16-16154619-C-T is Benign according to our data. Variant chr16-16154619-C-T is described in ClinVar as [Benign]. Clinvar id is 433396.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr16-16154619-C-T is described in Lovd as [Benign]. Variant chr16-16154619-C-T is described in Lovd as [Likely_benign].
• BS1: Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.0122 (1850/152242) while in subpopulation SAS AF= 0.0415 (200/4820). AF 95% confidence interval is 0.0368. There are 18 homozygotes in gnomad4. There are 900 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 18 AD,AR,Digenic gene
