The c.385C>T (p.P129S) alteration is located in exon 3 (coding exon 3) of the FNDC1 gene. This alteration results from a C to T substitution at nucleotide position 385, causing the proline (P) at amino acid position 129 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
