Genes affected

SERPINI2 (HGNC:8945): (serpin family I member 2) The gene encodes a member of a family of proteins that acts as inhibitors of serine proteases. These proteins function in the regulation of a variety of physiological processes, including coagulation, fibrinolysis, development, malignancy, and inflammation. Expression of the encoded protein may be downregulated during pancreatic carcinogenesis. Alternative splicing results in multiple transcript variants for this gene. [provided by RefSeq, Jan 2013]

Collection Method: clinical testing

The c.859C>T (p.L287F) alteration is located in exon 5 (coding exon 4) of the SERPINI2 gene. This alteration results from a C to T substitution at nucleotide position 859, causing the leucine (L) at amino acid position 287 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
