Collection Method:clinical testing

The c.157G>A (p.A53T) alteration is located in exon 3 (coding exon 3) of the PLA2G16 gene. This alteration results from a G to A substitution at nucleotide position 157, causing the alanine (A) at amino acid position 53 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
