The c.593A>T (p.Y198F) alteration is located in exon 3 (coding exon 2) of the SV2C gene. This alteration results from a A to T substitution at nucleotide position 593, causing the tyrosine (Y) at amino acid position 198 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
