Jul 20, 2022

The c.770C>T (p.S257L) alteration is located in exon 6 (coding exon 5) of the FNDC3B gene. This alteration results from a C to T substitution at nucleotide position 770, causing the serine (S) at amino acid position 257 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
