Ambry Genetics

May 24, 2023

The c.1221G>T (p.K407N) alteration is located in exon 6 (coding exon 4) of the SERPINA12 gene. This alteration results from a G to T substitution at nucleotide position 1221, causing the lysine (K) at amino acid position 407 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
