The c.1022A>G (p.D341G) alteration is located in exon 4 (coding exon 3) of the SERPINA11 gene. This alteration results from a A to G substitution at nucleotide position 1022, causing the aspartic acid (D) at amino acid position 341 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
