Dogs’ flat faces linked to skull condition

Studies of dog DNA have revealed a genetic mutation linked to flat face shapes which could help pave the way to diagnose an abnormal skull condition.

Researchers at the University of Edinburgh’s Roslin Institute analysed DNA samples from 374 pet dogs of various pedigree and mixed breeds. The animals underwent CAT scans as part of the project, producing detailed 3D images of their heads.

These allowed the scientists to take precise measurements of the shape of the dog’s skull and then pinpoint DNA variations associated with difmichael ferent head shapes. One variation, found to disrupt the activity of a gene called SMOC2, was strongly linked to the length of the dog’s face.

Scientists say screening children for changes in the SMOC2 gene could help to diagnose the condition.
