Justin Yerbury

Justin John Yerbury (born 1974) is an Australian molecular biologist who was spurred to follow a career in biological research when he discovered his family has the genetic form of Motor neuron disease. He was diagnosed in 2016 but continues to research.

Education and career

By his own admission, Yerbury "was not much of a scientist at school."^[1] He studied for a Bachelor of Commerce before playing professional basketball^[2] in the National Basketball League (NBL) for the Illawarra Hawks in 1995 and 1996^[3] while helping to run the family business.^[2]

In the late 1990s members of Justin's extended family were diagnosed and passed away from Motor Neurone Disease, also known as Amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease. Ninety to ninety-five percent of cases are considered sporadic, occurring randomly in the population. The remaining 5–10% of cases are Familial (Genetic) with one parent carrying the gene. Mutations of more than twelve genes have been found to cause the disease.^[4] Using genealogical information Yerbury traced suspected cases of motor neuron disease in his family to at least 1920 and possibly further back.^[5][2] He was prompted to return to university studies to further understand the disease.

In 2004 Yerbury obtained a BSc with 1st class honours from the University of Wollongong.^[6] He received his PhD from the same university in 2008 for a thesis titled: Characterisation of novel extracellular molecular chaperones and their effects on amyloid formation.^[7] He worked as a research assistant, lecturer and research fellow during his studies. During 2008 and 2009 he was an Australian Research Council (ARC) International Linkage Fellow at the University of Cambridge, UK. Yerbury has been a Discovery Early Career Researcher Award (DECRA) Postdoctoral Fellow at the University of Wollongong since 2012. He has spent the last decade studying the disease which affects around 2000 Australians, alongside his team at the Illawarra Health and Medical Research Institute (IHMRI), based at the University of Wollongong.^[8] His team of young researchers will carry on his work.^[1]

Personal life

Yerbury first knew of MND when his was uncle diagnosed in 1994. A cousin was diagnosed and died in 1997, he was 21 years old. During six-week period in 2002 his mother, grandmother and aunt passed away. Fifty percent of Yerbury's family carry a faulty SOD-1 gene. His youngest sister passed away from MND at 26 years old. Yerbury and his sister, Naomi, were tested for the gene; Naomi was clear but Yerbury's test was positive.^[5]

Yerbury was diagnosed with MND in 2016.^[9] His condition stabilised at first but he now requires around-the-clock care and has a ventilator to allow him to breathe. He was initially denied a suitable wheelchair and house modifications under the National Disability Insurance Scheme (NDIS), sparking an online crowd-funding campaign.^[10] After coming to the attention of Federal Labor MP Sharon Bird, he was provided with an appropriate wheelchair and some home modifications under the scheme.^[9] Yerbury's public profile has also highlighted others who encountered difficulties with the NDIS.^[9]

In January 2018 Yerbury's condition deteriorated significantly and he underwent a tracheostomy necessitating mandatory ventilation. To further facilitate his life support he also had a laryngectomy which means he is unable to speak. He now communicates by lip reading and using voice software coordinated by eye-gaze on his laptop computer.^[5]

In April 2017 Yerbury met Stephen Hawking, a world famous physicist and cosmologist who had MND for over fifty years. They discussed living with the disease and Yerbury's research.^[8][11][1]

Yerbury is married to Rachel Yerbury. They have two daughters: Talia Delphina Yerbury, born 1996 and Maddison Raini Yerbury, born 1998.

Research

“It was clear at the time that there was not enough understanding of the molecular basis of the disease to develop an effective therapeutic. I have, as a result dedicated myself to increasing the understanding of the origins of motor neurone disease”

— Dr Justin Yerbury, ^[12]

Yerbury is researching potential effective treatments for MND. His research interests include: protein misfolding, aggregation and neurodegenerative disease, protein aggregation and neuro-inflammation and the Propagation of protein misfolding, and protein homeostasis and Motor Neurone Disease.^[6] This video shows Yerbury demonstrating the role of protein folding in the progress of MND.^[13] His team studies single molecules of protein, grow cells and are carrying out some drug trials.^[14] He has been active in sharing his research not only with the academic community but also with those with MND and their families.^[15][16]

Yerbury has 51 research articles listed in PubMed^[17] in addition to many conference and other presentations.
