The RYR1 gene is responsible for producing the protein ryanodine receptor 1. This protein transport calcium ions to the cells for muscle contraction. When this receptor remains open for a long time, you would expect an excess of calcium ions which would result to muscle rigidity. The excess calcium ions would also increase body temperature and produce excess acid.
