The c.704T>C (p.L235P) alteration is located in exon 6 (coding exon 6) of the NT5DC3 gene. This alteration results from a T to C substitution at nucleotide position 704, causing the leucine (L) at amino acid position 235 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
