Collection Method:clinical testing

The c.257C>T (p.P86L) alteration is located in exon 3 (coding exon 3) of the PLA2G16 gene. This alteration results from a C to T substitution at nucleotide position 257, causing the proline (P) at amino acid position 86 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
