UCSD medical researchers discover molecular pathway that turns a juvenile heart into an adult heart

... called ASF/SF2 as a regulator of a calcium enzyme responsible for heart contraction and tissue growth. Mice born with mutated or absent ASF/SF2 had shortened contractive fiber that appeared locked in a contracted state, leading to sudden death. When ASF/SF2 was normal, heart development progressed normally. "T...

New genetic mutation linked to Parkinson's disease

... Researchers say the mutation on the LRRK2 gene is responsible for 5 percent of inherited Parkinson's disease cases. Tatiana Foroud, Ph.D., associate professor of medical and molecular genetics at Indiana University School of Medicine and principal investigator on the multi-site study, said the discovery has a ...

Scientists detect probable genetic cause of some Parkinson's disease cases

...o have the disease. Overall, the mutation could be responsible for up to 5 percent of Parkinson's disease in people with a family history of the disorder and may account for 1 to 2 percent of cases in individuals who do not have a family history of the disease. The researchers found a mutation in one copy of the...

Study identifies the most common genetic cause of Parkinson's disease

... a recently discovered Parkinson's disease gene is responsible for 5 percent of inherited Parkinson's disease cases. The finding opens the door to the possibility of genetic screening for the LRRK2 gene mutation, which is believed to be the most common genetic cause of inherited Parkinson's disease identified to...
