The c.686A>T (p.D229V) alteration is located in exon 2 (coding exon 2) of the FSCN3 gene. This alteration results from a A to T substitution at nucleotide position 686, causing the aspartic acid (D) at amino acid position 229 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
