The c.956C>T (p.A319V) alteration is located in exon 8 (coding exon 7) of the FNDC3B gene. This alteration results from a C to T substitution at nucleotide position 956, causing the alanine (A) at amino acid position 319 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
