Itis the most common genetic heart disease in the US and affects an estimated 1 in 500 people around the world. A protein called myosin acts as the molecular motor which makes the muscles in the heart contract. Researchers had suspected for some time that the R403Q mutation in some of the myosin genes is among those that play a role in causing HCM. But experiments using mice models failed to show that this was indeed the case.</p> Mon, 15 Oct 2018 19:03:54 +0000 priya.pajel@mail.mcgill.ca 89690 at /newsroom /newsroom/william-james-harvey Tue, 26 Feb 2019 16:59:44 +0000 Anonymous 24038 at /newsroom /newsroom/channels/news/every-breath-you-take-231519 Fri, 08 Nov 2013 21:34:02 +0000 christopher.chipello@mcgill.ca 19419 at /newsroom
