The c.1294G>A (p.V432I) alteration is located in exon 10 (coding exon 9) of the RABGAP1 gene. This alteration results from a G to A substitution at nucleotide position 1294, causing the valine (V) at amino acid position 432 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
