Stephen K. Duplock is a Geneticist based in North Terrace, Adelaide, SA 5001. He works with families dealing with rare inherited conditions, often where the cause runs through the genes and shows up in childhood.
His focus is on lysosomal storage disorders and other genetic conditions that can affect the way the body breaks down certain materials. In day-to-day terms, that can mean problems with the brain, movement, growth, and how organs work over time. Some of the conditions he looks after include Mucopolysaccharidosis Type 3 (MPS III, also called Sanfilippo Syndrome), Mucopolysaccharidoses (MPS), Gaucher disease, Tay-Sachs disease, and related conditions such as Gangliosidosis and Farber Lipogranulomatosis.
Genetic testing and careful checks matter a lot with these conditions. Stephen helps make sense of results and supports families as they plan next steps. At times, it can be a lot to take in. So the approach is usually steady and practical—explaining what a result can mean, what it doesn’t mean, and why more information may be needed.
Over time, he has worked with people who may be trying to confirm a diagnosis, understand symptoms, or learn what might come next. For many families, the biggest need is clarity. In many cases, that also includes looking at how the condition may affect other family members and what options might be available for managing risk.
When it comes to learning and staying current, he keeps up with new findings in genetic medicine and rare disease care. Research is a big part of this field because treatments and testing methods keep improving, even if progress can be slow for families waiting on answers.
Stephen also helps families connect the dots around current clinical study options when they’re relevant. Even when a study isn’t the right fit, getting that information can still help people feel more informed about what’s available.
His work is based in Adelaide, and his patients can come in with complex histories. The aim is simple: to support families with clear genetic guidance, based on sound testing, careful interpretation, and ongoing follow-up.
