Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2021The c.305C>T (p.A102V) alteration is located in exon 2 (coding exon 1) of the SV2C gene. This alteration results from a C to T substitution at nucleotide position 305, causing the alanine (A) at amino acid position 102 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
