Genes affected

LRRTM2 (HGNC:19409): (leucine rich repeat transmembrane neuronal 2) Predicted to enable neurexin family protein binding activity. Predicted to be involved in regulation of postsynaptic density 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. Is active in GABA-ergic synapse. Is integral component of postsynaptic specialization membrane. [provided by Alliance of Genome Resources, Apr 2022]

LRRTM2 links:

CTNNA1 (HGNC:2509): (catenin alpha 1) This gene encodes a member of the catenin family of proteins that play an important role in cell adhesion process by connecting cadherins located on the plasma membrane to the actin filaments inside the cell. The encoded mechanosensing protein contains three vinculin homology domains and undergoes conformational changes in response to cytoskeletal tension, resulting in the reconfiguration of cadherin-actin filament connections. Certain mutations in this gene cause butterfly-shaped pigment dystrophy. [provided by RefSeq, May 2016]
