Genes affected
MDGA2 (HGNC:19835): (MAM domain containing glycosylphosphatidylinositol anchor 2) Predicted to be involved in regulation of presynapse assembly; regulation of synaptic membrane adhesion; and spinal cord motor neuron differentiation. Predicted to act upstream of or within neuron migration and pattern specification process. Predicted to be located in extracellular region and plasma membrane. Predicted to be active in GABA-ergic synapse and glutamatergic synapse. [provided by Alliance of Genome Resources, Apr 2022]
