The c.1849A>T (p.M617L) alteration is located in exon 2 (coding exon 2) of the LINGO1 gene. This alteration results from a A to T substitution at nucleotide position 1849, causing the methionine (M) at amino acid position 617 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
