Collection Method: clinical testing

The c.748G>A (p.V250I) alteration is located in exon 6 (coding exon 6) of the NT5DC3 gene. This alteration results from a G to A substitution at nucleotide position 748, causing the valine (V) at amino acid position 250 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
