I could use kidney disease in patients with Joubert's syndrome


For the first time, scientists have identified how to prevent kidney disease in a life-restricted genetic condition, which can turn the way for personal treatment in the future.

Experts at the University of Newcastle, UK have shown in a cell model and in a mouse model that births for Joubert's syndrome could be used to prevent kidney damage in patients with CEP290 defective gene.

Joubert's syndrome is a brain disorder, causing varying degrees of physical, mental and sometimes visual impairment. The condition affects approximately one in 80,000 newborn children, and one third also has kidney failure.

Not all patients with Joubert's syndrome carry CEP290 gene, but those who develop kidney disease during their lifetime may require transplant or dialysis.

Significant development

The study, funded by Kidney Research UK, has found that it is possible to use a string of engineering DNA to detect editing machines and cells to avoid CEP290 mutation that causes harm to & Arena – a technique called excusation & # 39; .

Professor John Sayer, of the Institute of Genetic Medicine, Newcastle University led to the research published today (Friday, November 16) in the National Science Academy Transactions (PNAS).

He said: "This is the first time for births to be performed within the kidney, even in a mouse model, since the planning and delivery of the genes to the aren thought too hard of it and so on.

"Our research is an important step forward as we now know how we can offer therapy that corrects the gen error within the kidney cells and prevents the development of genetic kidney disease.

"This work shows the way towards personal genetic therapies in patients with inherited kidney disease."

The European study uses kidney cells by patients with Joubert's syndrome and a mouse model to move the research forward.

Experts used urine samples to grow kidney cells in the laboratory to see how cells respond to mean births. They also performed genes to prevent kidney disease in a mouse with Joubert and cholistod syndrome suffering from kidneys and kidney failure.

Challenging disease

Professor Sayer, Consultant Nephrologist at the Newcastle Hospital NHS Trust, said: "Treating the genetic kidney disease is challenging, as this requires the correction of basic generic deficiency and presentation treatment.

"We have shown that kidney disease in a mouse can dramatically be improved using this scan gene generator editing technology.

"This will mean that we can mean genetic errors that lead to hereditary kidney disease such as Joubert syndrome and we experience this technology in other mouse models before we move into patient studies.

"We expect that we will begin to experience treatment with patients who have a conversation in the next three years."

Scientists now look to work with a drug manufacturing company to bring the technology skipping into patient clinics.

The story of the patient

Asen Ahmed has the jungle of Joubert's syndrome and there is likely to be a need for transplantation of kidneys in the future.

Asher, from Fenham, Newcastle, was diagnosed with kidney damage five years ago and a number of drugs are well kept.

The 19-year-old has a range of medical issues due to his Joubert syndrome, including visual impairment, communication problems and difficulties with balance and coherence.

The girl has been instrumental in helping the research further as he has provided a number of samples over the years, allowing Newcastle scientists to grow kidney cells – without these the research would not have be possible.

Asher's mother Nabila, in Civil Service, said she welcomed the findings of a study led by the University of Newcastle as it will help provide better quality of life for patients in the future.

Mrs Ahmed said: "It is very important that research is carried out to Joubert's syndrome and kidney-related harm as it is hoped that this will prevent patients from getting kidney transplant in the future.

"Throughout the life of Asher, he has lived with the effects of Joubert's syndrome and five years ago he was diagnosed with kidney disease because he had a CEP290 gene.

"Asher on a number of tablets is good and this is an additional complication to an already difficult condition. We know that a future transplant will be likely and this is a cause of concern.

"We were happy for Asher to provide samples for the study as anything that helps to understand the condition further, it's worth doing so it's great to see positive results the study. "
