The c.238C>G (p.L80V) alteration is located in exon 4 (coding exon 3) of the NUDT13 gene. This alteration results from a C to G substitution at nucleotide position 238, causing the leucine (L) at amino acid position 80 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
