The c.853C>T (p.L285F) alteration is located in exon 2 (coding exon 1) of the VRTN gene. This alteration results from a C to T substitution at nucleotide position 853, causing the leucine (L) at amino acid position 285 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
