New genetic test could help to uncover causes of rare diseases
It has been difficult to identify the causes of rare conditions, as so few people are affected.

Multi-stage sequencing approach can pinpoint defective genes

Researchers from the University of Edinburgh have developed a method of identifying genetic mutations that are linked to a rare form of muscular dystrophy. The study was published in the journal EBioMedicine, and was funded by a number of organisations, including Muscular Dystrophy UK and the medical research council.

This new approach could allow for cheaper and faster diagnosis of the condition called Emery-Dreifuss muscular dystrophy (EDMD), which affects around one in 100,000 people worldwide, and can take many years to diagnose clearly. Researchers state that this method could also be modified to screen for gene mutations involved in other rare diseases.

According to previous research, mutations in six different genes cause EDMD, however, these mutations are found in less than half of people diagnosed with the disease. This implies that other genes could also trigger it.

Researchers say this new multi-stage sequencing approach has been designed to identify other genetic mutations that might cause EDMD.

The study initially revealed that more than 300 genes that could be involved in the disease, including ones that perform a similar function to the genes already known to cause EDMD. Some that were identified are also linked to other forms of muscular dystrophy.

When these genes were analysed alongside the genetic code of 56 people diagnosed with EDMD,  more than 20 new mutations that appear to cause the condition were uncovered. Researchers say that these are likely most of the remaining genes linked to EDMD.

Director of research and innovation at Muscular Dystrophy UK Dr Kate Adcock said: “We know that many people with neuromuscular conditions are living without a genetic diagnosis. This research could pave the way to help people to get a diagnosis earlier. This will help people to manage their condition thereby helping to provide a better quality of life.”

Rare chimp birth announced at Edinburgh Zoo

News Story 1
 The Royal Zoological Society of Scotland (RZSS) welcomed the birth of a critically endangered western chimpanzee on Monday 3 February at Edinburgh Zoo's Budongo Trail.

The baby girl will be named in the coming days through a public vote, and staff will carry out a paternity test during its first health check to determine the father.

Mother Heleen's first infant, Velu, was born in 2014, making this new baby only the second chimpanzee born in Scotland for more than 20 years.

Budongo Trail team leader Donald Gow said: "While we celebrate every birth, this one is particularly special because our new arrival is a critically endangered Western chimpanzee, a rare subspecies of chimpanzee."

BEVA offering free membership to vet students

The British Equine Veterinary Association (BEVA) is offering free membership to veterinary students. As part of a new initiative with the aim of encouraging more veterinary professionals into equine practice.

According to BEVA, less than one in ten veterinary students choose to work in equine practice. The association hopes that this initiative will provide insight into the field and the benefits of a career in equine medicine.

Benefits of membership include:
▪ access to a network of nearly 3,000 members
▪ special student rates to attend BEVA Congress
▪ online access to BEVA's Equine Veterinary Education (EVE) journal
▪ free access to the association's online learning platform
▪ free access to BEVA's practical veterinary apps
▪ exclusive discounts on a range of things from cinema tickets to grocery shopping.

BEVA will be releasing a series of short videos over the next few months from BEVA Council members, explaining what inspired them to work in equine practice.
