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]

Ambry Genetics

Dec 27, 2023

The c.1382A>T (p.N461I) alteration is located in exon 2 (coding exon 1) of the AMIGO1 gene. This alteration results from a A to T substitution at nucleotide position 1382, causing the asparagine (N) at amino acid position 461 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
