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.

Ambry Genetics

Oct 04, 2022

The c.142G>A (p.A48T) alteration is located in exon 3 (coding exon 2) of the HMSD gene. This alteration results from a G to A substitution at nucleotide position 142, causing the alanine (A) at amino acid position 48 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
