text: The deletion in chromosome 1 involved in TAR syndrome eliminates at least 200,000 DNA building blocks (200 kilobases, or 200 kb) from the long (q) arm of the chromosome, including a gene called RBM8A. Most people with TAR syndrome have the deletion in one copy of chromosome 1, which removes one copy of the RBM8A gene, and a mutation in the other copy of the RBM8A gene in each cell.
