Nov 13, 2023

The c.783C>A (p.H261Q) alteration is located in exon 2 (coding exon 2) of the FSCN3 gene. This alteration results from a C to A substitution at nucleotide position 783, causing the histidine (H) at amino acid position 261 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
