The c.66G>T (p.K22N) alteration is located in exon 2 (coding exon 1) of the SERPINB5 gene. This alteration results from a G to T substitution at nucleotide position 66, causing the lysine (K) at amino acid position 22 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
