The c.604G>A (p.G202R) alteration is located in exon 5 (coding exon 5) of the RELL2 gene. This alteration results from a G to A substitution at nucleotide position 604, causing the glycine (G) at amino acid position 202 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
