Genes affected

CBARP (HGNC:28617): (CACN subunit beta associated regulatory protein) Predicted to enable transmembrane transporter binding activity. Predicted to be involved in negative regulation of calcium ion-dependent exocytosis and negative regulation of voltage-gated calcium channel activity. Predicted to be located in synaptic vesicle membrane. Predicted to be integral component of membrane. Predicted to be active in plasma membrane. Predicted to colocalize with growth cone and secretory granule. [provided by Alliance of Genome Resources, Apr 2022]

CBARP-DT (HGNC:55285): (CBARP divergent transcript)

ACMG classification

Our verdict: Uncertain_significance. The variant received 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.772
