not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 20, 2024The c.1634G>A (p.R545H) 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 1634, causing the arginine (R) at amino acid position 545 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
