The c.1307G>A (p.R436K) alteration is located in exon 14 (coding exon 12) of the PPIG gene. This alteration results from a G to A substitution at nucleotide position 1307, causing the arginine (R) at amino acid position 436 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
