Nature of Mutation

DNA sequencing using the SOLiD technique identified a G to A transition at position 550 of the Sv2c transcript in exon 2 of 13 total exons. Multiple transcripts of the Sv2c gene are displayed on Ensembl and Vega. The mutated nucleotide causes a valine to methionine substitution at amino acid 107 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).

Protein Function and Prediction
The Sv2c gene encodes a 727 amino acid synaptic vesicle glycoprotein that plays a role in the control of regulated secretion in neural and insulin-secreting cells. SV2C positively regulates vesicle fusion by maintaining the readily releasable pool of secretory vesicles. SV2C contains twelve membrane-spanning domains. It is the receptor for the botulinium neurotoxin type A/BOTA and binds to this toxin at amino acids 529-566 (Uniprot Q69ZS6).
 
The V107M change occurs in the cytoplasmic N-terminus, and is predicted to be benign by the PolyPhen program.
