The c.2510A>G (p.Q837R) alteration is located in exon 21 (coding exon 21) of the R3HDM2 gene. This alteration results from a A to G substitution at nucleotide position 2510, causing the glutamine (Q) at amino acid position 837 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
