The c.971G>C (p.G324A) alteration is located in exon 10 (coding exon 9) of the ETV5 gene. This alteration results from a G to C substitution at nucleotide position 971, causing the glycine (G) at amino acid position 324 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
