Collection Method: clinical testing

The c.667C>T (p.R223C) alteration is located in exon 3 (coding exon 2) of the SERPINA11 gene. This alteration results from a C to T substitution at nucleotide position 667, causing the arginine (R) at amino acid position 223 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
