The c.170T>G (p.V57G) alteration is located in exon 3 (coding exon 2) of the SERPINB5 gene. This alteration results from a T to G substitution at nucleotide position 170, causing the valine (V) at amino acid position 57 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
