Mitochondrial diseases are common genetic disorders caused by defective energy production. They affect numerous organs and due to the clinical and genetic heterogeneity, obtaining a genetic diagnosis is often difficult yet crucial for the counselling of patients and their families. There are no cures but establishing a genetic diagnosis enables patients and their families’ access to genetic and reproductive counselling.
I am a State Registered Clinical Scientist and have spent the last 10 years working in the Nationally-Commissioned mitochondrial diagnostic laboratory in Newcastle. Our current testing strategy relies upon functional analysis of a muscle biopsy and selective candidate gene sequencing; whilst this strategy establishes a genetic diagnosis for many patients, approximately half our patients remain without a genetic diagnosis.  

I am particularly interested in paediatric mitochondrial disease, and spent much of my PhD improving the genetic diagnosis pathway for paediatric patients with mitochondrial disease through implementation of next-generation sequencing (NGS) technologies within a diagnostic setting.

For families who have lost a child, establishing a genetic diagnosis means that we can offer reproductive options to Mum and Dad such as prenatal testing by either chorionic villus biopsy or amniocentesis enables us to determine - from as early as 10 weeks of gestation - whether their subsequent pregnancies have inherited the same gene mutations.

My doctoral work has been remarkably successful in obtaining a rapid genetic diagnosis for patients and their families, and has enabled us to undertake prenatal testing for a number of families. 

A targeted approach to genetic diagnosis of paediatric complex I deficiency has shown that many patients' genetic defects affect a gene outwith those that encode the structural subunits and assembly factors of complex I, revealing that isolated complex I deficiency is considerably more genetically heterogeneous than initially suspected. We remain optimistic that we will be able to obtain a genetic diagnosis for these undiagnosed patients as our diagnostic algorithm continues to expand.
