Northern Midlands Medical Service general practitioner, Lucas Parry, will push his son Robbie, 3, up Mt Wellington's 21.1 kilometre incline next month.

The father and son duo will be participating in this year's Point to Pinnacle event on November 21, in an attempt to raise $20,000 for the Foundation For Angelman Syndrome Therapeutics.

Mr Parry said Robbie was diagnosed with Angelman Syndrome, a rare genetic disorder, when he was six months old.

"It can cause delayed development, absence of speech and problems with movement and coordination," he said.

"Only a few people in Tasmania have it and there's about a one in a 15,000 chance of getting it."

In early November, Robbie will undergo his eighth surgery at the Royal Hobart Hospital before rejoining his dad in training for the event a few weeks later.

Robbie's mother, Rachael Parry said scientists believed the disorder could potentially be cured in the future through the use of gene therapy and that human clinical trials were taking place around the world.

"It's really exciting to be living in an age where we can even talk about a genetic syndrome like this one day being cured," she said.

"Raising money for FAST could result in Robbie's life one day changing for the better, so it's very exciting and special cause for us."

Funds raised for FAST will support education, advocacy and research into treatments to improve symptoms and provide a cure.
