The c.4429G>A (p.G1477R) alteration is located in exon 14 (coding exon 14) of the ERICH3 gene. This alteration results from a G to A substitution at nucleotide position 4429, causing the glycine (G) at amino acid position 1477 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
