Collection Method: clinical testing

The c.187C>G (p.L63V) alteration is located in exon 2 (coding exon 2) of the PI16 gene. This alteration results from a C to G substitution at nucleotide position 187, causing the leucine (L) at amino acid position 63 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
