The c.1121T>G (p.L374W) alteration is located in exon 11 (coding exon 11) of the NT5DC3 gene. This alteration results from a T to G substitution at nucleotide position 1121, causing the leucine (L) at amino acid position 374 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
