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]

SYT9-AS1 (HGNC:56173): (SYT9 antisense RNA 1)

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.82).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.641 is higher than 0.05.
