The c.683A>C (p.N228T) alteration is located in exon 7 (coding exon 7) of the ALKBH6 gene. This alteration results from a A to C substitution at nucleotide position 683, causing the asparagine (N) at amino acid position 228 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
