WebThe RYR1 gene provides instructions for making a protein called ryanodine receptor 1 (also called the RYR1 channel). This protein is part of a group of related proteins called ryanodine receptors, which form channels that, when turned on (activated), release positively charged calcium atoms (ions) from storage within cells. WebIn terms of the genetics of Ullrich congenital muscular dystrophy, there are mutations in the genes COL6A1, COL6A2, and COL6A3.
