The c.736C>G (p.R246G) alteration is located in exon 7 (coding exon 7) of the ALKBH6 gene. This alteration results from a C to G substitution at nucleotide position 736, causing the arginine (R) at amino acid position 246 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
