The c.2521G>A (p.G841R) alteration is located in exon 21 (coding exon 20) of the ZC3H7A gene. This alteration results from a G to A substitution at nucleotide position 2521, causing the glycine (G) at amino acid position 841 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
