The c.2497C>T (p.L833F) alteration is located in exon 16 (coding exon 15) of the MTMR4 gene. This alteration results from a C to T substitution at nucleotide position 2497, causing the leucine (L) at amino acid position 833 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
