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.224C>A (p.T75N) 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 224, causing the threonine (T) at amino acid position 75 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
