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]

The c.196C>A (p.P66T) alteration is located in exon 5 (coding exon 4) of the SERPINF2 gene. This alteration results from a C to A substitution at nucleotide position 196, causing the proline (P) at amino acid position 66 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
