The c.1103A>C (p.K368T) alteration is located in exon 4 (coding exon 4) of the SERPINA9 gene. This alteration results from a A to C substitution at nucleotide position 1103, causing the lysine (K) at amino acid position 368 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
