The c.1222A>T (p.N408Y) alteration is located in exon 5 (coding exon 5) of the SERPINA9 gene. This alteration results from a A to T substitution at nucleotide position 1222, causing the asparagine (N) at amino acid position 408 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
