Collection Method: clinical testing

The c.166G>A (p.V56I) alteration is located in exon 2 (coding exon 2) of the UNC5A gene. This alteration results from a G to A substitution at nucleotide position 166, causing the valine (V) at amino acid position 56 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
