The c.391G>C (p.G131R) alteration is located in exon 1 (coding exon 1) of the PDZRN4 gene. This alteration results from a G to C substitution at nucleotide position 391, causing the glycine (G) at amino acid position 131 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
