The c.674A>G (p.H225R) alteration is located in exon 6 (coding exon 5) of the SERPINB5 gene. This alteration results from a A to G substitution at nucleotide position 674, causing the histidine (H) at amino acid position 225 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
