Genes affected

COL6A5 (HGNC:26674): (collagen type VI alpha 5 chain) This gene encodes a member of the collagen superfamily of proteins. The encoded protein contains multiple von Willebrand factor A-like domains and may interact with the alpha 1 and alpha 2 chains of collagen VI to form the complete collagen VI trimer. Polymorphisms in this gene may be linked to dermal phenotypes, such as eczema. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2013]

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.479 is higher than 0.05.
