The c.511G>A (p.A171T) alteration is located in exon 2 (coding exon 2) of the FSCN3 gene. This alteration results from a G to A substitution at nucleotide position 511, causing the alanine (A) at amino acid position 171 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
