The c.2998G>A (p.G1000R) alteration is located in exon 16 (coding exon 15) of the ARHGAP20 gene. This alteration results from a G to A substitution at nucleotide position 2998, causing the glycine (G) at amino acid position 1000 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
