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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 29, 2022The c.301C>A (p.Q101K) alteration is located in exon 3 (coding exon 2) of the SERPINI2 gene. This alteration results from a C to A substitution at nucleotide position 301, causing the glutamine (Q) at amino acid position 101 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
