The c.385C>G (p.R129G) alteration is located in exon 5 (coding exon 4) of the WIPF3 gene. This alteration results from a C to G substitution at nucleotide position 385, causing the arginine (R) at amino acid position 129 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
