Genes affected
LRRC4 (HGNC:15586): (leucine rich repeat containing 4) Predicted to be involved in modulation of chemical synaptic transmission and synapse organization. Predicted to act upstream of or within synapse organization. Predicted to be located in neuron spine and postsynaptic membrane. Predicted to be active in Schaffer collateral - CA1 synapse; glutamatergic synapse; and plasma membrane. Predicted to be integral component of postsynaptic density membrane. [provided by Alliance of Genome Resources, Apr 2022]
SND1 (HGNC:30646): (staphylococcal nuclease and tudor domain containing 1) This gene encodes a transcriptional co-activator that interacts with the acidic domain of Epstein-Barr virus nuclear antigen 2 (EBNA 2), a transcriptional activator that is required for B-lymphocyte transformation. Other transcription factors that interact with this protein are signal transducers and activators of transcription, STATs. This protein is also thought to be essential for normal cell growth. A similar protein in mammals and other organisms is a component of the RNA-induced silencing complex (RISC). [provided by RefSeq, Jul 2016]
