Collection Method:clinical testing

The c.1066G>A (p.V356I) alteration is located in exon 6 (coding exon 5) of the NTN5 gene. This alteration results from a G to A substitution at nucleotide position 1066, causing the valine (V) at amino acid position 356 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
