The c.352G>T (p.V118F) alteration is located in exon 1 (coding exon 1) of the NTN3 gene. This alteration results from a G to T substitution at nucleotide position 352, causing the valine (V) at amino acid position 118 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
