The c.1321G>A (p.G441R) alteration is located in exon 9 (coding exon 7) of the ZNF496 gene. This alteration results from a G to A substitution at nucleotide position 1321, causing the glycine (G) at amino acid position 441 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
