Genes affected

LRRTM1 (HGNC:19408): (leucine rich repeat transmembrane neuronal 1) Predicted to be involved in regulation of postsynaptic density assembly and regulation of presynapse assembly. Predicted to act upstream of or within several processes, including long-term synaptic potentiation; negative regulation of receptor internalization; and positive regulation of synapse assembly. Located in endoplasmic reticulum and growth cone. Is active in GABA-ergic synapse. Is integral component of postsynaptic specialization membrane. [provided by Alliance of Genome Resources, Apr 2022]

LRRTM1 links:

CTNNA2 (HGNC:2510): (catenin alpha 2) Enables actin filament binding activity. Involved in negative regulation of Arp2/3 complex-mediated actin nucleation; regulation of neuron migration; and regulation of neuron projection development. Located in cytoplasm. Implicated in complex cortical dysplasia with other brain malformations. [provided by Alliance of Genome Resources, Apr 2022]
