The c.482T>A (p.V161D) alteration is located in exon 3 (coding exon 3) of the METTL11B gene. This alteration results from a T to A substitution at nucleotide position 482, causing the valine (V) at amino acid position 161 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
