The c.112G>A (p.V38M) alteration is located in exon 3 (coding exon 3) of the NT5C3B gene. This alteration results from a G to A substitution at nucleotide position 112, causing the valine (V) at amino acid position 38 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
