Apr 24, 2023

The c.802C>T (p.P268S) alteration is located in exon 11 (coding exon 9) of the PPIG gene. This alteration results from a C to T substitution at nucleotide position 802, causing the proline (P) at amino acid position 268 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
