Genes affected

SYT15 (HGNC:17167): (synaptotagmin 15) This gene encodes a member of the Synaptotagmin (Syt) family of membrane trafficking proteins. Members of this family contain a transmembrane region and a C-terminal-type tandem C2 domain. Unlike related family members, the encoded protein may be involved in membrane trafficking in non-neuronal tissues. Two trancript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Jul 2008]

SYT15-AS1 (HGNC:56167): (SYT15 antisense RNA 1)

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.24235308).
