The c.350T>C (p.M117T) alteration is located in exon 5 (coding exon 4) of the FNDC3B gene. This alteration results from a T to C substitution at nucleotide position 350, causing the methionine (M) at amino acid position 117 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
