Host Sydney has created an awareness and fundraising campaign for a rare genetic disorder, Friedreich's Ataxia, after a staff member's son was diagnosed with the disease.

Host broadcast production director Kaija Wall's son Jai was diagnosed with the disease which strikes the nervous system, leading to muscle weakness, diabetes and heart disease.

The 'Lend Us Some Muscle' campaign is hoping to promote awareness of Friedreich's Ataxia.

The campaign, called 'Lend Us Some Muscle', is asking people to pledge their support on social media and spread the word by striking a body builder pose. People are also being asked to help fund research into the incurable disease.

So far, the campaign has raised $11,800 with donations coming in from Australia, the US and the UK.

Those involved in the campaign were Host, ILK, Biggie Smalls, The Feds, Josh Logue, Method Studios, Sound Reservoir, Lisa Bailey, Billy Plummer, Outpost and One Green Bean.

The initiative is not the first time the industry has rallied around one of their own. Last year, McCann created a campaign to support 20-year old industry member Will Chapman who needed a double lung and heart transplant.
