Bulldogs’ tails give insight into rare human disorder
Bulldogs, French bulldogs and Boston terries all share a feature not found in other breeds - a short, kinked tail or “screw tail”.
Scientists identify link between ‘screw tails’ and Robinow syndrome

Researchers in the US have made a link between the bulldog’s curly tail and a rare inherited disorder in humans.

Scientists from the University of California, Davis, School of Veterinary Medicine, found a common mutation in bulldogs and French bulldogs that is similar to genetic changes in the human disease, Robinow syndrome.

They believe that understanding this common mutation in these popular dog breeds could give more insight into this rare condition. The study has been published in the journal PLOS Genetics.

“It’s a very rare human disease but very common in dogs, so this could be a model for the human syndrome,” said professor Danika Bannash from UC Davis.

Bulldogs, French bulldogs and Boston terries all share a feature not found in other breeds - a short, kinked tail or “screw tail”. This is because all three breeds are missing the vertebrae that makes up the tail bone.

To learn more about the genetics associated with screw tail breeds, researchers analysed the genome of 100 dogs, of which 10 were screw tails.

From over 12 million individual differences, the researchers identified one mutation in a gene called DISHEVELLED 2 or DVL2. The variant was present in 100 per cent of the bulldogs and French bulldogs sampled, and it was also common in Boston terriers.

In humans, mutations in the related DVL1 and DVL3 genes are linked to Robinow syndrome - a disorder that causes a short, wide “babyface”, spinal deformities and short limbs - traits also shared by screw tail breeds.

The study also identified a key biochemical step in the pathway disrupted by the mutation, suggesting that a common molecular defect is responsible for the appearances of both Robinow patients and screw tail dog breeds.

Big Butterfly Count returns

News Story 1
 The world's biggest survey of butterflies is back for 2020!

Butterfly Conservation's Big Butterfly Count launches on Friday, 17 July and will run until Sunday 9 August. Members of the public can get involved by downloading the Big Butterfly Count App or recording results on a downloadable sheet available from bigbutterflycount.org/.

'It's a fantastic activity for people from three to 103 years and we'd encourage everyone to take 15 minutes in an appropriate outdoor space during sunny conditions to simply appreciate the nature around them and do their bit to help us understand butterfly populations,' said a Butterfly Conservation spokesperson.

WellVet reopens ticket sales to online conference platform

Following the success of its online conference, the organisers behind WellVet Weekend have re-opened ticket sales to allow new delegates to access session recordings and its online networking platform.

The day-long conference saw more than 360 veterinary professionals mix activity sessions with personal development CPD, all hosted within a virtual conference platform. Now, with more than 500 minutes of CPD available, the resource is being re-opened to allow full access to the session recordings until May 2021.

Sessions are aimed at providing delegates with a range of proactive wellbeing tools to explore to find ways of improving their mental and physical health. Tickets are limited in number and on sale at wellvet.co.uk until 30th August 2020.
