Lisa G. Riley is a Medical Geneticist based in Sydney, NSW, Australia. She helps families when a child or adult is dealing with a suspected genetic condition. Genetics can feel overwhelming, especially when symptoms are complex or not yet fully explained, and the aim here is to make things clearer.
Lisa works with people who may have rare inherited disorders, including conditions that affect the brain and nerves, muscles, growth and development, and energy production in the body. In many cases, this includes babies and children with ongoing health problems, plus families who are trying to understand what might be going on and what to expect next.
Her work often covers a wide range of symptoms and diagnoses such as epilepsy and seizure disorders, developmental delay, and muscle weakness. She also looks at genetic causes behind conditions like mitochondrial disorders (problems with how the body makes energy), inherited anaemias, and some hearing or vision issues. At times, she helps untangle diagnoses where there are multiple body systems involved, for example cardiomyopathy (heart muscle issues), hearing loss, or features affecting the face, eyes, skin, or growth.
Some of the conditions she may discuss include syndromes linked with early-onset seizures and movement issues, lactic acidosis, Leigh syndrome, West syndrome, Turner syndrome, and several forms of inherited retinal or optic problems. She may also be involved when achalasia, lung or breathing difficulties in infancy, or other rare early childhood health challenges need a genetic explanation.
Lisa’s experience is in supporting diagnosis and helping families understand genetic results, including what they can mean for the person right now and for future planning. She also provides guidance on how testing fits together with medical history and symptoms. Education is in medical genetics, with a practical focus on turning test information into clear, step-by-step answers.
