Michael T. Gabbett

Michael Terrence Gabbett is an Australian clinical geneticist and academic. He holds academic titles at a number of universities in South East Queensland. Gabbett is known for contributing to discovering the genetic basis of semi-identical (sesquizygotic) twins  and defining the clinical features and molecular cause of Temple-Baraitser syndrome.

Early life
Gabbett attended high school at Marist College Ashgrove, where he was awarded the Australian Student Prize and was accepted into the University of Queensland to study medicine.

Service to science
Gabbett was joint first author on the paper that demonstrated biallelic mutations in the mismatch repair genes are associated with malfomations of the brain. Gabbett and colleagues helped define the oculoauriculofrontonasal syndrome. In 2015, Gabbett and his molecular genetic colleagues demonstrated the cause of Temple Baraitser syndrome, a condition that Gabbett clinically defined seven years earlier. Gabbett and Nick Fisk were able to postulate, with supportive molecular evidence, how semi-identical (sesquizygotic) twinning is the result of a single egg being fertilized by two sperm from the same man.

Service to professional organisations
Gabbett has contributed to authorship of the Australasian clinical genetics training curriculum, and led the 2022 working party that made recommendations to medical schools on their genomics curriculum. For three years (2015-2018), he was chair of the scientific programme and the local organising committees (Lead Fellow) for RACP Congress, the annual scientific meeting of the Royal Australasian College of Physicians. Gabbett has served as president of the Australasian Association of Clinical Geneticists (2017-2019). From 2018 to 2022, Gabbett sat on Council of the Human Genetics Society of Australasia as Treasurer.
