Collection Method:clinical testing

The c.494G>C (p.G165A) alteration is located in exon 4 (coding exon 4) of the PCTP gene. This alteration results from a G to C substitution at nucleotide position 494, causing the glycine (G) at amino acid position 165 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
