Collection Method: clinical testing

The c.1091C>T (p.A364V) alteration is located in exon 3 (coding exon 3) of the RTN4RL2 gene. This alteration results from a C to T substitution at nucleotide position 1091, causing the alanine (A) at amino acid position 364 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
