The c.637C>A (p.L213M) alteration is located in exon 2 (coding exon 1) of the C9orf106 gene. This alteration results from a C to A substitution at nucleotide position 637, causing the leucine (L) at amino acid position 213 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
