The c.690C>A (p.F230L) alteration is located in exon 3 (coding exon 2) of the SV2C gene. This alteration results from a C to A substitution at nucleotide position 690, causing the phenylalanine (F) at amino acid position 230 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
