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 GeneticsOct 18, 2021The c.1169G>A (p.R390Q) alteration is located in exon 14 (coding exon 11) of the SYTL3 gene. This alteration results from a G to A substitution at nucleotide position 1169, causing the arginine (R) at amino acid position 390 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
