The study – requiring cheek swabs of mothers and their children – aims to gather genetic samples from 10,000 people right across Australia.
One of the world's most serious complications during pregnancy and birth, cerebral palsy is a disability that affects one in every 500 children worldwide, and the consequences are life long.
Over the next two years the researchers will test 5000 participants from families affected by cerebral palsy, while the other 5000 without an affected child will consist of a control group.
"Our study will investigate a key issue behind cerebral palsy: whether genetic factors make women more vulnerable to environmental risks that affect the brain of their unborn child. These risks – such as prematurity and infections – combined with genetic susceptibility mean that babies could be at double jeopardy of cerebral palsy," says research leader Professor Alastair MacLennan, Head of Obstetrics & Gynaecology at the University of Adelaide . PhD student Michael O'Callaghan is the national coordinator of the trial.
"Recent studies by our group suggest that cerebral palsy may be associated with genetic and other mutations that may increase blood clotting within the brain," says Professor MacLennan, who is also head of the South Australian Cerebral Palsy Research Group, the world's leading research group into the causes of cerebral palsy.
"An association between cerebral palsy and different types of herpes virus infection – such as cold sores and chicken pox – has also been discovered in South Australian studies.
"The next step is to see if this is true in a much larger population, comparing the genetics of both mother and child," he says.
People with cerebral palsy lack control of their movement and posture as a result of brain injury in the neuro-motor region. The symptoms vary greatly in severity, ranging from poor muscle co-ordination to quadriplegia.
Cerebral palsy is usually present from birth. The injury to the brain does not get worse over time.
"It was once thought that cerebral palsy was caused by low oxygen levels during birth. However, this is rarely the case," Professor MacLennan says.
"Obstetric care and caesarean deliveries have increased six-fold over the last 50 years, but the incidence of cerebral palsy cases has remained the same. Most of the cases are associated with problems during pregnancy and possible genetic susceptibility. Currently there is no cure or way to prevent cerebral palsy," he says.
"If our research confirms that there are genetic mutations that can lead to cerebral palsy, specific disease preventions may be available for individuals.
"In the future, gene therapy may allow doctors to alter the aberrant genes in a mother or fetus, or specific drugs could be used to counter the effect of genetic mutations and ultimately prevent a child from developing cerebral palsy before birth.
"Knowledge of a patient's genetic makeup and tailored administration of anti-inflammatory drugs before and during pregnancy may be possible. Immunisation against viral infections also may be a future option when this preventative therapy is available," he says.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
