Summary
Male breast cancer (MBC) is rare and understudied. Using the latest technology, this study will identify new genes which cause familial MBC to aid in the genetic counselling and risk assessment of an affected man and his family. The frequency of these novel genes, and all known breast cancer genes will be assessed in a second group of affected men as well as families with an increased female breast cancer risk. By better understanding the cause of MBC, we can improve its management.
Identification And Characterisation Of Novel FLT3-ITD Co-operating Mutations

Summary
Acute myeloid leukaemia is a cancer of the blood and bone marrow. We have identified new genes that act with the known oncogene FLT3-ITD in myeloid disease. We will examine in detail how these new genes contribute to the development of AML. This will aid in the development of new therapies for groups of AML patients with these mutations.
Defining The Leukaemogenic Mechanism For GATA2 T354M, A New Predisposing Mutation In Familial MDS/AML

Funding Amount
$631,883.00
Summary
A successful approach for identification of cancer genes has been to study the 5-10% of cases occurring in families with inherited predisposition to develop cancer. Unlike solid tumours, few cancer-causing mutations are known for haematological cancers. We have found a new mutation in 3 families in a gene (GATA2) not previously associated with familial acute myeloid leukaemia. We will explore how this mutation causes leukaemia to help better understand the more common non-inherited leukaemias.
Identification Of Genes Responsible For Familial Predispositions To Haematological Malignancies

Summary
A successful approach to the identification of cancer genes has been to study the 5-10% of cases that occur in families with an inherited predisposition to develop cancer. In contrast to solid tumors, few cancer-causing germ-line mutations have been identified for hematological cancers. We are using cutting edge technologies to identify blood cancer genes in a collection of both Australian and international families and comparing them to similar sporadic cancers.
Analysis Of Circulating Tumour DNA For Mutational Characterisation And Tracking Disease Progression In Multiple Myeloma

Summary
Multiple myeloma is cancer of plasma cells in the bone marrow and presents at multiple sites with dissimilar genetic information (GI) across these sites. Invasive biopsies of multiple sites are required to determine the GI. Cancer cells shed small amounts of DNA into the blood stream and this circulating DNA (ctDNA) contains GI from multiple cancer sites. This project will evaluate the utility of ctDNA to determine GI and to predict treatment response in MM patients.
The Landscape Of Cancer Genes And Associations With Prognosis In Breast Cancer Diagnosed In Premenopausal Women

Summary
Using state of the art technology, the purpose of this project is understand the implications of known cancer mutations in breast cancer diagnosed in premenopausal ER-positive breast cancer. Mutations are abnormalities in the DNA of genes that can provide a signal for uncontrolled growth, a hallmark of cancer. The unique aspect of this project is use of tissue samples from patients who were diagnosed with breast cancer at a young age. This information will help us develop new treatments.
Detection Of Somatic Mutations In Sporadic Epilepsies

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.
Somatic Retrotransposition Drives Neoplastic Mutagenesis In Glioblastoma Multiforme

Funding Amount

Summary
Retrotransposons are mobile genes that copy-and-paste themselves in our genome. Previously thought to represent “junk DNA”, retrotransposons are increasingly found to play major roles in biology. In a recent landmark publication in Nature, we demonstrated that retrotransposons move in the healthy human brain. In the current study, we will use cutting-edge technologies to determine whether brain cancer can occur as a result. This will provide new perspectives of the genetic basis for cancer.
Co-operation Between GATA2 Mutation Or Expression And RAS Signalling In AML

Funding Amount
$860,601.00
Summary
We have identified a gene GATA2 which, when mutated, can lead to leukaemia (blood cancer). We will collect samples worldwide from families and individuals that carry GATA2 mutations and have developed leukaemia, and will screen for other genetic changes that contribute to leukaemia. We have also identified a novel group of patients who have a low GATA2 activity and who also have mutations in the RAS gene, a known contributor to leukaemia. We will determine how these cooperate to cause leukaemia.
The Role Of Somatic Mutations In CCCTC-binding Factor (CTCF) Binding Sites In Cancer

Funding Amount

Summary
The three dimensional organisation of genomic DNA has been recognised to play a crucial role in maintaining the stability and function of human cells. In cancer this organisation is often perturbed as a result of mutations to proteins that govern this process. This project will examine how mutations in the DNA may potentially alter the three dimensional organisation of cancer genomes and will identify links between these mutations with cancer development and patient prognosis.
