The c.130G>A (p.G44R) alteration is located in exon 2 (coding exon 2) of the ARHGAP45 gene. This alteration results from a G to A substitution at nucleotide position 130, causing the glycine (G) at amino acid position 44 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
