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]
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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 10, 2024The c.236C>T (p.P79L) alteration is located in exon 2 (coding exon 1) of the SERPINA4 gene. This alteration results from a C to T substitution at nucleotide position 236, causing the proline (P) at amino acid position 79 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
