SNX29 also known as RUNDC2A, is a 375 amino protein that contains one RUN domain. RUNDC2A is encoded by a gene that maps to human chromosome 16p13.13, which encodes over 900 genes and comprises nearly 3% of the human genome. The GAN gene is located on chromosome 16 and, witHuman, Mouseutation, may lead to giant axonal neuropathy, a nervous system disorder characterized by increasing malfunction with growth. The rare disorder Rubinstein-Taybi syndrome is also associated with chromosome 16, as is Crohn's disease, which is a gastrointestinal inflammatory condition.
