Ambry Genetics

Sep 26, 2023

The c.53T>G (p.V18G) alteration is located in exon 7 (coding exon 1) of the LINGO2 gene. This alteration results from a T to G substitution at nucleotide position 53, causing the valine (V) at amino acid position 18 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
