Genes affected

SYT9 (HGNC:19265): (synaptotagmin 9) Predicted to enable several functions, including calcium ion binding activity; phospholipid binding activity; and syntaxin binding activity. Predicted to be involved in calcium-ion regulated exocytosis; cellular response to calcium ion; and regulation of secretion by cell. Predicted to be located in clathrin-coated endocytic vesicle membrane. Predicted to be active in hippocampal mossy fiber to CA3 synapse; plasma membrane; and secretory vesicle. Predicted to be integral component of synaptic vesicle membrane. [provided by Alliance of Genome Resources, Apr 2022]

The c.708G>C (p.Q236H) alteration is located in exon 3 (coding exon 3) of the SYT9 gene. This alteration results from a G to C substitution at nucleotide position 708, causing the glutamine (Q) at amino acid position 236 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
