The c.145G>A (p.G49R) alteration is located in exon 1 (coding exon 1) of the RAB36 gene. This alteration results from a G to A substitution at nucleotide position 145, causing the glycine (G) at amino acid position 49 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
