A Functional Assay To Classify Genetic Variants In Lynch Syndrome

Summary
At least one person in every 1000 is affected by Lynch syndrome, in which faulty DNA repair machinery causes high rates of cancer. People with Lynch syndrome can have their risk of cancer cut substantially with regular screening. However, we often struggle to understand whether people with 'non-standard' DNA sequences in particular genes actually have Lynch syndrome. This project develops a simple test that will tell clinicians whether a given sequence change relates to Lynch syndrome or not.
Detection Of Somatic Mutations In Sporadic Epilepsies

$1,256,166.00
Summary
Finding genetic causes of epilepsies is essential for refining treatments and genetic counseling. Genetic mutations may occur after fertilization (somatic mutations). These can be difficult to detect by routine genetic tests. We aim to identify somatic mutations by: very deep sequencing of blood to find low concentrations of mutations, analysing DNA from the cerebrospinal fluid, and analysing DNA obtained from the back of the nose which is closely related to brain tissue.
A Worldwide Study Of Cancer Risk For Lynch Syndrome

Funding Amount
$710,761.00
Summary
People with the genetic Lynch syndrome are more likely to get cancer but we cannot accurately predict who will get cancer and when. Doctors need this information to improve cancer prevention. Large collaborative studies are needed for this research. We have agreement from the 115 researchers to combine, into a single resource, 8,863 family trees of Lynch syndrome. We will analyse this data to determine the risk of cancer and whether it differs by sex, age, or nationality.
Risks And Benefits Of Breast Cancer Screening: BreastScreen WA Cohort Study Of Overdiagnosis And Breast Cancer Mortality
Funder
National Health and Medical Research Council
Funding Amount
$201,524.00
Summary
Overdiagnosis is the major downside of screening for breast cancer. This occurs when screening detects cancers that would not have caused symptoms in the woman's lifetime. This study aims to quantify the amount of overdiagnosis that occurs in the Australian breast cancer screening program (BreastScreen)
Characterization Of A Novel Epigenetic Boundary And Long Range Epigenetic Modifications Specific To FMR1 Expansion Carriers With Behavioural And Cognitive Disorders - Implications For Earlier Diagnosis And Treatment.

Funding Amount

Summary
Fragile X Syndrome (FXS) is the most common form of inherited intellectual disability and autism and is caused by a faulty switch in the gene FMR1. We have discovered new DNA regions important in FXS. The project aims to explain how these new regions regulate the FMR1 gene. This is essential for the discovery and validation of new avenues for earlier diagnosis, treatments and therapies for children and adults with FMR1 disorders and also for informing reproductive decisions.
About 14,000 cases of bowel cancer occur annually in Australia despite the availability of life-saving screening. Most people do not receive recommended screening colonoscopy. We will look at why people at high-risk avoid screening and why people at average risk seek unnecessary screening. We will analyse family history and contacts with the healthcare system that impact screening decisions. We will determine the impact of screening on reducing the number of new cases and deaths.
Expanding Diagnostic Approaches For Lynch Syndrome

Funding Amount
$1,269,355.00
Summary
Currently, there are ~1,000 families who have attended Family Cancer Clinics across Australia who have the hallmarks of having Lynch syndrome, a hereditary bowel cancer syndrome, but who have no gene defect identified, i.e. their cancer is unexplained. Clinicians are challenged by these “Lynch-like” patients as their family cancer risk is unknown. Our research has identified new gene defects in Lynch-like patients. Our aim is to optimise clinical testing approaches for Lynch-like patients.
Novel Fragile X Syndrome Prevalence Estimates In 100,000 Australian Newborns, Prognostic And Health-economic Outcomes: A Retrospective Newborn Screening Study
Funder
National Health and Medical Research Council
Funding Amount
$769,866.00
Summary
Fragile X syndrome (FXS) is a common heritable cause of intellectual disability and co-morbid autism, caused by epigenetic silencing of the FMR1 gene. This will be the world’s largest FXS mutation prevalence study conducted in 100,000 newborns using a novel test targeting epigenetic changes, and will also explore the prognostic outcomes, costs and benefits associated with FXS newborn screening, providing conclusions regarding expanding the current newborn screening in Australia to include FXS.
Point-of-care HPV-DNA Testing For Cervical Cancer Screening In High-burden, Low-resource Settings

National Health and Medical Research Council
Funding Amount
$891,184.00
Summary
We will undertake the first field evaluation of a novel, newly-available, easy to use, and highly accurate point-of-care (POC) test for high-risk human papillomavirus (hrHPV) infection that will allow trained health staff to identify women at increased risk of cervical cancer and to provide same-day cervical cryotherapy for pre-cancer lesions identified on clinical examination.
Evaluating Cancer Screening: Context, Evidence, Values And Ethics
Funder
National Health and Medical Research Council
Funding Amount
$572,460.00
Summary
The research and clinical communities are divided over whether certain forms of cancer screening do more harm than good. This project asks: What is the right thing to do about cancer screening now? Using robust qualitative methodologies, we will study real cases of cancer screening and analyse their ethical implications. Drawing on this data and analysis, we will produce tools to help policy-makers, consumers and professionals make good decisions about cancer screening in future.
