Collection Method: clinical testing

The c.667C>G (p.R223G) alteration is located in exon 3 (coding exon 2) of the SERPINA11 gene. This alteration results from a C to G substitution at nucleotide position 667, causing the arginine (R) at amino acid position 223 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
