The c.2427T>G (p.F809L) alteration is located in exon 2 (coding exon 2) of the C9orf131 gene. This alteration results from a T to G substitution at nucleotide position 2427, causing the phenylalanine (F) at amino acid position 809 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
