Genes affected

SERPINA4 (HGNC:8948): (serpin family A member 4) Predicted to enable serine-type endopeptidase inhibitor activity. Predicted to be involved in negative regulation of endopeptidase activity. Located in extracellular exosome. Biomarker of diabetic retinopathy. [provided by Alliance of Genome Resources, Apr 2022]

SERPINA4 links:

SERPINA5 (HGNC:8723): (serpin family A member 5) The protein encoded by this gene is a member of the serpin family of proteins, a group of proteins that inhibit serine proteases. This gene is one in a cluster of serpin genes located on the q arm of chromosome 14. This family member is a glycoprotein that can inhibit several serine proteases, including protein C and various plasminogen activators and kallikreins, and it thus plays diverse roles in hemostasis and thrombosis in multiple organs.

The c.711G>C (p.E237D) alteration is located in exon 3 (coding exon 2) of the SERPINA4 gene. This alteration results from a G to C substitution at nucleotide position 711, causing the glutamic acid (E) at amino acid position 237 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
