Genes affected
SERPINF2 (HGNC:9075): (serpin family F member 2) This gene encodes a member of the serpin family of serine protease inhibitors. The protein is a major inhibitor of plasmin, which degrades fibrin and various other proteins. Consequently, the proper function of this gene has a major role in regulating the blood clotting pathway. Mutations in this gene result in alpha-2-plasmin inhibitor deficiency, which is characterized by severe hemorrhagic diathesis. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 18, 2023The c.472G>A (p.G158S) alteration is located in exon 6 (coding exon 5) of the SERPINF2 gene. This alteration results from a G to A substitution at nucleotide position 472, causing the glycine (G) at amino acid position 158 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
