The c.745C>T (p.R249W) alteration is located in exon 3 (coding exon 3) of the ALKBH4 gene. This alteration results from a C to T substitution at nucleotide position 745, causing the arginine (R) at amino acid position 249 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
