The c.1711G>A (p.V571I) alteration is located in exon 2 (coding exon 2) of the LINGO1 gene. This alteration results from a G to A substitution at nucleotide position 1711, causing the valine (V) at amino acid position 571 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
