Although most of the genetic variants seemed to occur spontaneously and not be inherited, the researchers did observe mutations in six genes known to be linked to a similar movement disorder known as hereditary spastic paraplegia. Owned and operated by AZoNetwork, © 2000-2020. Long thought to be a disease of environmental triggers, researchers have found rare mutations in single genes that can cause some cases of cerebral palsy. In an article published in Nature Genetics, researchers confirm that about 14% of all cases of cerebral palsy, a disabling brain disorder for which there are no cures, may be linked to a patient’s genes and suggest that many of those genes control how brain circuits become wired during early development. Write CSS OR LESS and hit save. In about 12% of the cerebral palsy patients in the study, the causal genetic mutations were acquired by chance, not inherited from either parent. 5, Clinical OMICs Magazine Volume 7, Issue No. Now, scientists have identified mutations in single genes that can be responsible for at least some cases of cerebral palsy, according to a new study led by researchers at Washington University School of Medicine in St. Louis, the University of Arizona College of Medicine in Phoenix, and Yale University. The U.S. National Institute of Neurological Disorders and Stroke has more on cerebral palsy. 3, Clinical OMICs Magazine Volume 7, Issue No. News-Medical.Net provides this medical information service in accordance The causes of cerebral palsy have long been debated and often are attributed to in utero infections, premature birth, or brain injury to the baby near or during delivery, usually from a lack of oxygen. In … between patient and physician/doctor and the medical advice they may provide. Ultimately, 11.9% of cerebral palsy cases among those studied could be attributed to randomly occurring mutations, the study found. Some previous studies have suggested that variants in certain genes could increase a child’s risk of having cerebral palsy, perhaps accounting for up to 14% of cases, but earlier studies had minimal controls and functional validation of the highlighted mutations was not carried out. In about 2% of the patients in the study, the mutations were inherited from both parents, neither of whom had cerebral palsy. In many cases, vision, hearing, and sensation are also affected. Signs and symptoms vary among people and over time.

The remaining 86% of cases could have environmental causes, or contributions from other genetic variations that will require a larger study to reveal, or a combination of genetic mutations and environmental interactions that the researchers are still working to understand. Long thought to be a disease of environmental triggers, researchers have found rare mutations in single genes that can cause some cases of cerebral palsy. The scientists were able to show that introducing mutations of the same genes into fruit flies caused the insects to have movement difficulties that resemble those common in people with cerebral palsy, a common neurodevelopmental disorder. “As we come to recognize the role of genetics in cerebral palsy, we open the door for new treatments, earlier diagnosis and intervention, which could lead to greatly improved quality of life.”. ", Added Jin: "We are continuing to study cerebral palsy patients and their parents, and as our sample size increases, we may begin to be able to measure the contributions from less common recessive and dominant mutations passed down from one or both parents. In addition to the genetic screen of cerebral palsy families, the scientists assessed the function of the genes that were linked to disease risk by studying the orthologous genes in fruit flies. In this interview, Dr. Hadi Yassine and Dr. Hassan Zaraket speak about their research into whether COVID-19 will become a seasonal virus. People used to think that CP was mainly caused by lack of oxygen during the birth process. The researchers also noted that some of the genes newly implicated in cerebral palsy have in past research been associated with autism, intellectual disability and epilepsy. 4, Clinical OMICs Magazine Volume 7, Issue No. Cerebral palsy patients had higher levels of potentially harmful de novo mutations than their parents, and about 12% of cerebral palsy cases in the study could be … "In a nutshell, the flies couldn't walk.
