The c.89C>T (p.T30M) alteration is located in exon 2 (coding exon 1) of the FNDC4 gene. This alteration results from a C to T substitution at nucleotide position 89, causing the threonine (T) at amino acid position 30 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
