Collection Method: clinical testing

The c.82C>T (p.R28W) alteration is located in exon 2 (coding exon 1) of the NUDT13 gene. This alteration results from a C to T substitution at nucleotide position 82, causing the arginine (R) at amino acid position 28 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
