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.

Dec 14, 2023

The c.158A>T (p.D53V) alteration is located in exon 3 (coding exon 2) of the HMSD gene. This alteration results from a A to T substitution at nucleotide position 158, causing the aspartic acid (D) at amino acid position 53 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
