Thymidine kinase 2 deficiency (https://www.mito.org.au/types-of-mito/tk2d/), or TK2d, is a rare type of mitochondrial disease that mainly affects the muscles and can impact movement, swallowing, speech and breathing. Symptoms can begin in infancy or childhood, but may also first appear during the teenage years or adulthood.
In this episode, we explore how changes in the TK2 gene affect mitochondrial DNA and energy production, why symptoms can vary so widely between people, and how TK2d is inherited. We also discuss the tests that may be used during diagnosis, genetic counselling, ongoing monitoring and emergency planning, as well as current research and emerging therapies.

Let's talk ADOA
Autosomal dominant optic atrophy (https://www.mito.org.au/types-of-mito/adoa/), or ADOA, is a rare inherited condition that affects the optic nerves and can lead to gradual changes in vision. It is one of at least 350 known types of mitochondrial disease.
In this episode, we explore how ADOA can affect central and colour vision, the role of the OPA1 gene, how the condition can be inherited, and the tests that may be used during diagnosis. We also discuss ADOA plus, where some people may experience additional symptoms affecting hearing, balance, movement, muscles or nerves, as well as ongoing monitoring, support and current research.

Let’s talk NARP
Neurogenic weakness with Ataxia and Retinitis Pigmentosa, also known as NARP, is a rare type of mitochondrial disease, mito for short. It affects mitochondria, the parts of our cells that make energy, and it commonly impacts the brain, nervous system and muscles. NARP often begins in the first few months or years of life, but it can also start in the teenage years or adulthood.
In this episode, we unpack what NARP can look like day to day. We explain symptoms such as muscle weakness and low muscle tone, balance and coordination changes, sensory nerve symptoms like numbness or burning pain, and vision changes that may worsen over time, including night or side-vision loss. We also explore why experiences can differ from person to person, even with the same genetic change, and point you towards support and planning resources linked in the episode description.
The information in this episode is based on Mito Foundation resources, including the NARP information page (https://www.mito.org.au/types-of-mito/narp).
