Researchers from the University of Sheffield as part of the AMBRoSIA biobank, have found higher than expected genetic changes in a group of 100 MND patients. 42 of the 100 people (21%) with MND in this study showed some form of variants in the 44 known MND-linked genes. 35 of these 42 people (93%) had no family history of MND which shows that some familial and sporadic cases can share the same genetic cause of disease. The researchers propose that a test for the most common MND genes could be offered to all patients in the future, whether they have a family history of the disease or not. This could impact on disease sub-classification and clinical care, especially when drug companies are developing approaches to treat MND by specifically targeting associated genes to reduce the damage caused to motor neurons.
