The c.122G>A (p.R41Q) alteration is located in exon 2 (coding exon 1) of the RAB3D gene. This alteration results from a G to A substitution at nucleotide position 122, causing the arginine (R) at amino acid position 41 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
