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]

LOC105371100 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -13 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BP6: Variant 16-16211880-A-C is Benign according to our data. Variant chr16-16211880-A-C is described in Lovd as [Benign].
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0347 (5264/151556) while in subpopulation AFR AF= 0.0451 (1855/41108). AF 95% confidence interval is 0.0434. There are 106 homozygotes in gnomad4. There are 2453 alleles in male gnomad4 subpopulation. Median coverage is 30. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 106 AD,AR,Digenic gene
