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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.96).
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0229 (3471/151664) while in subpopulation AFR AF= 0.0406 (1682/41416). AF 95% confidence interval is 0.039. There are 48 homozygotes in gnomad4. There are 1648 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 48 gene
