Genes affected

AMIGO1 (HGNC:20824): (adhesion molecule with Ig like domain 1) Predicted to enable potassium channel regulator activity. Predicted to be involved in several processes, including heterophilic cell-cell adhesion via plasma membrane cell adhesion molecules; homophilic cell adhesion via plasma membrane adhesion molecules; and nervous system development. Predicted to act upstream of or within positive regulation of synapse assembly. Predicted to be located in dendrite and neuronal cell body membrane. Predicted to be integral component of membrane. Predicted to colocalize with voltage-gated potassium channel complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
