SLC26A2 is a gene that provides instructions for making a protein involved in transporting certain molecules across cell membranes. This protein plays a crucial role in the movement of sulfate and other anions, which are important for various biological processes, including the formation of cartilage and bone. Mutations in the SLC26A2 gene can lead to health issues, such as diastrophic dysplasia, a type of skeletal dysplasia characterized by short stature and joint problems. Understanding the function of SLC26A2 helps researchers explore potential treatments for related genetic disorders.
