The c.1246C>T (p.L416F) alteration is located in exon 11 (coding exon 11) of the MRS2 gene. This alteration results from a C to T substitution at nucleotide position 1246, causing the leucine (L) at amino acid position 416 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
