The c.859C>G (p.L287V) alteration is located in exon 1 (coding exon 1) of the ACTL8 gene. This alteration results from a C to G substitution at nucleotide position 859, causing the leucine (L) at amino acid position 287 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
