Collection Method:clinical testing

The c.423C>A (p.F141L) alteration is located in exon 7 (coding exon 7) of the NT5C3B gene. This alteration results from a C to A substitution at nucleotide position 423, causing the phenylalanine (F) at amino acid position 141 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
