The c.4798G>C (p.G1600R) alteration is located in exon 1 (coding exon 1) of the RIMBP3C gene. This alteration results from a G to C substitution at nucleotide position 4798, causing the glycine (G) at amino acid position 1600 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
