Genes affected

CLSTN3 (HGNC:18371): (calsyntenin 3) Predicted to enable calcium ion binding activity. Predicted to be involved in positive regulation of synapse assembly and positive regulation of synaptic transmission. Predicted to act upstream of or within several processes, including chemical synaptic transmission; positive regulation of protein localization to synapse; and synapse assembly. Predicted to be located in postsynaptic density. Predicted to be part of protein-containing complex. Predicted to be active in several cellular components, including GABA-ergic synapse; glutamatergic synapse; and postsynaptic membrane. Predicted to be integral component of postsynaptic density membrane. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0015180409).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.0546 is higher than 0.05.
