Retina E-news-Dic-chem ride for sight 2015

A very successful 27th Ride for Sight was held on Sunday February 15th and for this we need to thank Dis-Chem Pharmacies, our naming sponsor, the City of Ekurhuleni our generous hosts, the secondary sponsors of prizes and services, our co-organizers Springs Wheelers, Hamnet, Benoni Red Cross and the hundreds of volunteers who assist on the day.

Special mention must be made of our volunteer organizing committee many of whom have been with us since the inception of the ride in 1989. The entire proceeds from the event go directly to supporting the patients services project at the University of Cape Town and over the last 27 years has generated more than R5m to help find treatments for retinal genetic blindness.

 

 

SCIENCE AND RESEARCH NEWS

THE OPHTHALMOLOGY CONGRESS 2015

The annual OSSA congress was held in Durban from 12th to 14th March 2015 at the ICC in Durban.

An awareness table and delegates fees were kindly sponsored by Rhyno Kriek, conference organizer. We gave a presentation on Genetic research and testing in South Africa to the Optometric and Ophthalmic Assistants program. Interest in our awareness material was gratifying and our stock was totally depleted by the end of the congress.

SCIENTIFIC AND MEDICAL ADVISORY BOARD MEETING

Our annual SMAB meeting was held at the congress and the meeting was co-chaired by Professor Ramesar and Dr Linda Visser. Invited guests were Professors Colin Barnstable and Joyce Tobran- Tink from Penn State University USA. They both gave excellent papers at the congress on genetics, Epigenetics and biological pathways in retinal degeneration.

SMOKING AND GENETIC RISK FACTORS FOR AMD

Past smokers and smokers developed wet Age Related Macular Degeneration [AMD] almost 4,9 and 7.7 years earlier then never smokers. Genetic mutations in various genes resulted in earlier age of onset ranging from 2,8 to 12.2 years. Published in the JAMA – Ophthalmology February 2015.

ANNUAL REPORT ON THE RDD RESEARCH PROJECT AT U.C.T.
By Prof Jacquie Greenberg

We have 3 postgraduate students undertaking RDD research projects. This promises to yield some interesting results over the next 3 years.

MSc student Dr Johann Baard who is due to complete his dissertation early in 2015 entitled: “Genetics of Age-related Macular Degeneration and Stargardt disease in South African populations.”

PhD student: Ms Lisa Roberts is hoping to finalize her research in 2016, on her challenging Whole Exome Sequencing (WES) project, a large portion of which was completed at the NIH in the lab of Prof Anand Swaroop at the NEI on her project entitled: “The genetic basis of inherited retinal diseases in indigenous Southern African populations.”

PhD student: Ms Stacey Moses is working on a project entitled: “Towards identifying the precise molecular pathogenesis underlying the disease phenotype in individuals carrying a mutation in the spliceosomal factor, PRP8.”

In addition, over and above their projects; Lisa Roberts performed the statistical analysis of the MYO7A founder mutation for Usher Syndrome in 185 Africans. She supervised the initial screening by an NRF intern, Ms. Siddiqah George and then completed the final screening of the remaining samples. Lisa wrote the manuscript which was submitted for publication early in 2015.

Stacey Moses and other NRF interns electronically captured all RDD patient data that has arrived at UCT/Human Genetics unaccompanied by samples. All this data has been compiles into a searchable spread-sheet to assist with RDD epidemiological information.

SAMPLES RECEIVED AND ARCHIVED IN 2014:

101 samples were received from 51 new families and 50 old families. Of the 101 samples, 50 were saliva samples. 6 Skin biopsies were also received. Five DNA sample were isolated by the NHLS and sent to us for archiving and possible future screening.

MICROARRAY/NGS TESTS AND VERIFICATIONS:

13089 database entries were entered onto our database in 2014 and pathogenicity investigation was performed for each variant identified, prior to delivery of the official laboratory report.

3 results were received from Manchester (NGS) from samples sent in 2013.

One of the results was verified and confirmed in the family. The other 2 results were not confirmed for various reasons.

7 results were received from Asper Biotech in Estonia: Verification of the all these results from the November 2013 batch was completed.

14 DNA samples were sent for Microarray testing to Estonia in June (5 self-funded + 9 funded by Retina SA). 3 samples were sent for Next Generation Sequencing to Manchester in June. Some results of these are still pending.

OTHER TESTS:

1 additional test was performed for family mutation: 1 PCR and 2 Sequencing 8 Quick 7 tests – done by NHLS.

In total, 40 diagnostic reports were created in 2014 and 24 were delivered. We responded to over 100 queries from patients, counsellors and clinicians:

GENERAL NUMBERS AS AT FEBRUARY 2015:

3222 DNA samples archived from 1420 Families in the UCT RDD Database

279 RDD families are completely characterised = 19.65%

242 RDD families are in ‘diagnostic mode’ = 17.04%

193 families stand to benefit from current gene therapy trials: 5 RPE65; 6 AIPL1, 8 MYO7A; and remarkably: 174 ABCA4.

To date, 403 individuals have received a result (+’ve , -‘ve, or inconclusive)

CLINICAL TRIALS- AT LAST!

We are assisting in the attempt to bring 2 clinical trials for Stargardt Dystrophy to South Africa. Patients with a diagnosis of STGD or Cone rod dystrophy who are interested in being considered for possible inclusion, if we are successful, should contact Claudette at email:medefindt@intekom.co.za.

All RD patients, particularly those under the age of 40 should have a genetic diagnosis- do you?

CHOROIDEREMIA TREATMENT RECEIVES ORPHAN DRUG STATUS

Nightstar has received Orphan drug designation in both Europe and America for the treatment that it is developing for Choroideremia. This gene therapy treatment was originally developed by Professor Robert McLaren and showed good results in an early trial last year.

Orphan Drug Designation, which is intended to facilitate drug development for rare diseases, provides benefits to companies- including regulatory support in development activities such as protocol assistance, reduced fees, tax incentives and several years of market exclusivity for the product once it is approved. [ Editor- Orphan disease definition differs between countries, in Europe it is less than 1 in 2000 people, in the USA it is 1 in 1500, in Japan 1 in 2 500. Most retinal degenerative conditions excluding AMD would therefore be regarded as Orphan diseases.]

CHARLES BONNET SYNDROME.

These visual hallucinations are receiving much needed attention. Hallucinations can be geometric shapes or even complex visual details and scenes. They occur in cases of advanced visual loss and can be very disturbing. It is estimated that more than 10 % of patients see them and they are largely underreported.

RETINAL-SCAN ANALYSIS PREDICTS ADVANCE OF AMD

In a study published in the November issue of Investigative Ophthalmology & Visual Science, researchers derived a formula that predicts, with high accuracy, whether a patient with mild or intermediate AMD will progress to the wet stage. By adding a computerized image- processing step that analyses data from SD-OCT scans ophthalmologists will be able to predict a patient’s likelihood of progressing to the wet stage within 1 year, 3 years or 5 years.

LISA ROBERTS IN NEI NEWS

Lisa Roberts our chief Scientific officer at the Division of Human Genetics at UCT recently spent time in the USA hunting for Gene mutations responsible for RD in our Black South African families. Her trip was highlighted in the NEI NEWS. Excerpt from the article:

Lisa Roberts conducts research on eye diseases, including rare genetic diseases that run through southern African families. She spent November in the NEI Neurobiology Neurodegeneration & Repair Laboratory (NNRL) learning techniques that she’ll apply in her genetic research at home. The ultimate goal of the Retinal Degenerative Disease (RDD) project is to identify the molecular mechanisms of diseases causing vision loss in South Africans. The project has a strong emphasis on translational research, which means that many of its findings are translated back to patients. For example, when a genetic mutation causing vision loss is identified in a family, the family is offered diagnostic testing, including carrier testing and predictive testing. This enables life planning and reproductive options, and is essential for participation in any gene-based therapy trials.

She and her colleagues on this project have strong relationships with the patient-driven action group, Retina South Africa, and they regularly provide research feedback to patients by hosting several awareness days each year and contributing to Retina South Africa’s e-newsletter.

Ms. Roberts came to NNRL in collaboration with Dr. Anand Swaroop, chief of the NNRL, to perform Whole Exome Sequencing analysis on 56 individuals from 16 indigenous black African families with different retinal diseases using NNRL’s Illumina HiSeq DNA sequencer. In addition to performing this specific research project, she wanted to master the skills to use this cutting-edge technology. The sequencer is not yet widely available in South Africa, and her new skills would build capacity for genomic research there. Their next step is analyzing the vast amounts of sequencing data they have generated.

“I am thankful for the support of Retina South Africa. They provided some of my travel funding and assisting with patient recruitment. I am in debt to all the patients with retinal degenerative diseases in South Africa who participate in our research program,” said Ms. Roberts. “I am very grateful to Drs. Ramesar and Greenberg from the Division of Human Genetics for this exciting opportunity, and to Dr. Swaroop for the use of the technology and equipment in his lab.”

The results obtained from this research will be applied to hundreds of indigenous black South Africans suffering from vision loss. In addition, Ms. Roberts hopes the results of this project will inspire other investigations into retinal diseases for the people of broader Southern Africa.

RETINA SA WESTERN CAPE – HUMAN RIGHTS DAY PICNIC

On 21st March 2015 (Human Rights Day) our branch hosted a picnic in the beautiful Hout Bay area. We invited all members and their families and friends to come and spend the afternoon with us and socialize with each other in a relaxed and informal environment.

We had a great group of diverse and interesting people from all walks of life. There were young and old people all mingling and sharing their life experiences with each other, and there were lots of kids who were having a great time playing together in the beautiful surroundings.

We had two guest speakers, namely; Dr. Janet Hodgson and Jennifer Webster. Janet is the author of several books, some of which deal with her life and experiences of living with AMD. Jennifer is an enthusiastic blogger who has a unique and inspirational way of sharing her life experiences of living with MD. Both these ladies are great inspirations to us all and have a lot to share with the world.

We were also lucky enough to have both Georgina Sampson and Vincent Daniels present at the picnic, and as two of the original founders of our organization, we were very glad to have them share their experiences with us. We were also very fortunate to have some of the major role players in the blind and visually impaired sector with us for the afternoon.

We then had a lucky draw with some wonderful prizes which were donated by some very special people and organisations who have shown us great support. Everyone was really excited and some great prizes were won.

We had some great feedback from all who attended and we missed those who could not attend, and we look forward to a few other great events and get-togethers over the rest of the year.

THANK YOU BAUSCH AND LOMB FOR YOUR CONTINUED SUPPORT OF OUR WORK.
