Researchers at the Monash Institute of Medical Research (MIMR) and the University of Melbourne have for the first time created adult induced pluripotent stem cells from patients with the rare genetic disorder, Friedreich's Ataxia.
It is expected these stem cells will lend deeper insight into the disease and its progression, and open up the possibility of a stem cell-based treatment.
Friedreich's ataxia is an autosomal recessive genetic disorder, meaning sufferers have two copies of the abnormal FXN gene, which results in reduced synthesis of the FXN mRNA and its corresponding protein, frataxin.
The disease is characterised by neurodegeneration, leading to speech and gait problems, and deterioration of heart function. It affects around 30,000 people globally.
The researchers, co-led by Paul Verma from the MIMR and Alice Pébay and Mirella Dottori from the University of Melbourne, produced the stem cells from skin fibroblasts.
Read more about Paul Verma's research into induced pluripotent stem cells.
The resulting stem cells possessed the characteristic genetic traits associated with Friedreich's ataxia, and can be induced to give rise to two cell types that are affected by the disease, peripheral neurons and cardiomyocytes.
Producing stem cells such as this can give tremendous insight into the progression of a disease as they represent ideal models and can be used to develop high-throughput drug screening assays.
The stem cells could also be part of a treatment for the disease. The researchers demonstrated that functional versions of the genes involved in Friedreich's ataxia can be inserted into the stem cells, resulting in proper expression of the frataxin protein in neurons differentiated from the cells.
This raises the possibility of a therapeutic treatment involving patient-derived induced pluripotent stem cells with the genetic abnormality corrected which can be the source of cells for transplantation.
The research could also aid in the treatment of other diseases, said Verma.
“Due to the number of symptoms experienced by people with FA, including diabetes and heart disease, this resource could be applied to developing treatment for those conditions and helping even more people," he said.
The study was published in the journal Stem Cell Reviews and Reports.

I have 2 older sisters with FA they found out in the teens and the disease has gotten worse. They both are confined to a wheelchair now and can't do much of anything. Their speech. Is slurred and writing skills are almost impossible now. They are ages 42 and 43. Please email me if there is a treatment that could help.

My daughter Brittany is 22 yrs old. She was diagnosed at the age of 15 with Friedreich's Ataxia. We have done hours of research on stem cell treatment in China. She is looking for any help possible.Please help before she gets worse. We are currently having fundraisers/benefits to raise funds to cover any treatments. I will do what ever it takes to help you to help us. Is there going to be a clinical trial for this. Please e-mail me with any imformation on a clinical trial.

My daughter is 17 years old and diagnosed with Freidrich's Ataxia in 2002 and now she is on wheel-chair. Last year, she went through stem-cell treatment in China but DID NOT help her case. But still I want to try anything to help her. So, please let me know whatever is out there and I can be reached at: ChotoKashi@Gmail.Com
By the way, I live in Toronto, Canada

My best friend Michelle H was falling constantly at 2 yrs and worsening. She was diagnosed at 4, her back was fused at 18, and by 28 she was fully in the wheelchair. She is a wonderful poet, writer of songs and stories, which is how we met online. Since then, I've discovered she has been mostly isolated by adoptive parents who won't even take her to the ER when she broke her nose. I understand they are tired and have heard them say "Let me live my own life!" We have been desperately trying via internet to find some way to give her her life back. Please help.

Hello,
My cousin suffers from FA and has scoliosis and arched feet. She uses wheel chair but has no heart complications. Are there any approved clinical trials which can help her. Any information or direction would be deeply appreciated. She currently lives in India.
Judy
Hi my 2 daughtes were diagnosed in 2000 at the age of 24 and 25, they are 10 months apart , were diagnosed about 10 months apart as the simptoms were starting about 10 months apart and are just starting to use a walker or wheelchair for shopping or outings. They can still walk some and have no signs of heart stress or enlargment as of yet. They do have arched feet now. No diabetes either. We would love more information on treatment and any testing being done. Other than the FA they are both pretty healthy and stay very active considering.
Thank you and God Bless

My name is Yvonne Maalderink, from the Netherlands, by my son Dave almost 18 years old and still running good,,, is 4 years ago discovered that he Friedreich's ataxia has, he now uses Defirpone but we see little of, I am very intrested in your study, I also like to know whether this has been tried on humans and the reaction of the patient, I would like to be kept Sincerely Yvonne Maalderink
Debbie Thomson
My name is Debbie from Tasmania and I was told I am the only person diagnosed with FA in this state. I was diagnosed 3 years ago, no cardiac problems or diabetes but have had numerous falls and fractures. I am studying social work at uni and desperately seeking support groups located in Aus and would love to be involved in any clinical trials available.
I have 3 children who are yet to be tested. Are there any medicines or herbal supplements I could be taking to offset symptoms ?
Sincerely Debbie Thomson.

I have two daughters that have FA both use wheelchairs there ages are 31 and 27. Please let me know about trials or any info available. Thank you for your time. Jody
Um Kultum
Medical Report: Chatib Um Kultum (id# 90006798-4) and Elchatib Chatam (Id# 99984095-2)
The above-named sisters were seen by me on 31/5/09. Their neurological condition is similar. Both have an onset of disease around mid to late teenage with difficulties in coordination. The condition is slowly progressive to involve limb ataxia, speech difficulties, and scoliosis. The elder sister Um Kultum (age 33) is now wheel chair bound, while the young sister (age 23) is walking with marked difficulty.
Examination revealed cerebellar dysarthria, disdiadokokinesis, and intention tremor. There was no nystagmus. Tendon reflexes were absent, but Babinski sign was present bilaterally. There was reduced vibration and position sensation. Scoliosis was noted in both.
The family history is that of consanguinous parents and a younger brother who seem to show early signs of the disease.
The above clinical combination is very suspicious for Friedrich Ataxia, a diagnosis already suggested by previous physicians. The DNA of Chatam was tested here in Hadassah and expansion of the Frataxin gene was found, compatible with the clinical diagnosis of Friedrich Ataxia.
Both patients should have cardiac follow up because of the frequent involvement of the heart in this condition (over 50% have cardiomyopathy). The disease is progressive but does not affect the cognitive functions. Thus, both ladies are encouraged to continue with their education and work as much as possible.
Currently there is no treatment for this recessively-inherited condition. Idebenone given at high doses was recently shown to have some positive effects in patients with Friedrich Ataxia especially on the cardiac complication. This medication is not yet available in Israel but I am aware of plans to add it to the list of approved drugs in Israel in the near future.
