GPM6A (Glycoprotein M6A): GPM6A is a gene that encodes a glycoprotein predominantly expressed in the nervous system. It plays a vital role in neurite outgrowth and the formation of neuronal networks, as well as in the development and maintenance of the myelin sheath, which is crucial for efficient nerve signal transmission. GPM6A is associated with neurological disorders such as schizophrenia and bipolar disorder, owing to its involvement in neuronal plasticity and myelination. Alterations in GPM6A expression or function may impact synaptic connectivity and brain function, potentially contributing to these neuropsychiatric conditions.
