The c.861G>C (p.L287F) alteration is located in exon 6 (coding exon 4) of the MTCL1 gene. This alteration results from a G to C substitution at nucleotide position 861, causing the leucine (L) at amino acid position 287 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
