Genes affected
SYTL3 (HGNC:15587): (synaptotagmin like 3) The protein encoded by this gene belongs to a family of peripheral membrane proteins that play a role in vesicular trafficking. This protein binds phospholipids in the presence of calcium ions. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 16, 2021The c.845G>T (p.G282V) alteration is located in exon 11 (coding exon 8) of the SYTL3 gene. This alteration results from a G to T substitution at nucleotide position 845, causing the glycine (G) at amino acid position 282 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
