Genes affected

HMSD (HGNC:23037): (histocompatibility minor serpin domain containing) This gene encodes a serpin-domain containing protein that may function as a serine protease inhibitor. This gene is primarily expressed in cells of myeloid lineage. A polymorphism in this gene may result in the expression a splice variant that encodes a minor histocompatibility antigen.

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.95).
