SLC6A12 is a gene that encodes a protein responsible for transporting certain amino acids across cell membranes. This protein is part of the sodium-dependent neurotransmitter transporter family and plays a crucial role in the reabsorption of amino acids in the kidneys, particularly glycine and serine. Mutations in the SLC6A12 gene can lead to various health issues, including hyperaminoaciduria, a condition characterized by elevated levels of amino acids in the urine. Understanding this gene is important for studying its implications in kidney function and potential metabolic disorders.
