The c.1433G>C (p.G478A) alteration is located in exon 11 (coding exon 11) of the ACTR8 gene. This alteration results from a G to C substitution at nucleotide position 1433, causing the glycine (G) at amino acid position 478 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
