SLC44A1 (Solute Carrier Family 44 Member 1) is a gene that encodes a protein responsible for transporting choline, an essential nutrient involved in producing the neurotransmitter acetylcholine and maintaining cell membrane structure. This transporter supports key processes like nerve signaling and cell health. Disruptions in choline transport may affect brain function and have been linked to neurological disorders such as Alzheimer’s disease.
