Genes affected

SYT11 (HGNC:19239): (synaptotagmin 11) This gene is a member of the synaptotagmin gene family and encodes a protein similar to other family members that are known calcium sensors and mediate calcium-dependent regulation of membrane trafficking in synaptic transmission. The encoded protein is also a substrate for ubiquitin-E3-ligase parkin. The gene has previously been referred to as synaptotagmin XII but has been renamed synaptotagmin XI to be consistent with mouse and rat official nomenclature. [provided by RefSeq, Apr 2010]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.46G>T (p.V16L) alteration is located in exon 2 (coding exon 2) of the SYT11 gene. This alteration results from a G to T substitution at nucleotide position 46, causing the valine (V) at amino acid position 16 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
