Faulty gene link to peanut allergy

Scientists have found a gene they believe is behind the cause of allergies to peanuts.

Children who suffer from a faulty Filaggrin gene are three times more likely to develop an allergy to the nut, researchers at Dundee University found.

It is the first time that a genetic change has been linked to the allergy, Dr Sara Brown from the university said.

The researchers found that one in five of all sufferers of such allergies had a defective Filaggrin.

The number of people suffering from such an allergy has soared since the 1980s.

The findings come after the team found that the Filaggrin gene was also a significant factor in eczema and asthma.
