Girl, 6, diagnosed with mystery neurological condition after struggling to walk, talk

A fundraising campaign has been launched for a 6-year-old girl who is believed to be the only child in the world suffering from a rare and unknown neurological condition.

Eva Turner was diagnosed with the mystery disorder after her parents noticed her struggles learning to walk, talk and sleep.

She didn’t start walking until she was nearly 2 years old, but was very slow and struggled to balance.

She also developed a tremor when overexerting and was diagnosed with an unknown condition a year later.

Doctors said a faulty gene which had never been seen before was causing Eva’s problems.

THE family of a six-year-old with a rare and unknown neurological condition affecting her balance and speech have launched a fundraising campaign to find a cure. Eva Turner, who lives near Wallingford, has difficulty with her balance and speech and struggles to process new information. But despite being behind her peers in terms of development she continues to make progress and enjoys horse-riding, swimming, trampolining, crafts and cooking. Her parents Carla and Adam have launched a '1 in 20,000' fundraising campaign, through their charity Eva's Friends, to raise awareness of rare neurological conditions and work towards a cure.

“The day she walked those seeds of doubt surrounding her development really started to take hold," Carla Turner, Eva's mom, said. "Instead of finding her balance and taking tentative steps, Eva would desperately hold onto something before making a quick dash, using her shoulders to direct herself, before hanging on to something else for dear life.

"We met her neurologist for the first time and within minutes he told us that there was a problem but he didn’t know what," she said. “He did however suggest it was likely to be quite rare. It was at that very moment that my heart started to break; just a small crack, but the start of a crack which now, every day, gets a little bit bigger."

“The condition had never been seen before; there was no reference to it in any medical literature and there was no one else that was known to have it," Carla Turner said. “Eva is the only known person in the world with this particular genetic variation - but to us she is just our little girl.”

But the problems didn’t stop there for Eva, who later received a secondary diagnosis of Rett Syndrome - another rare neurological condition caused by a mutated gene.

She is unable to jump, run or walk great distances without bursting into tears - and struggles with speech and getting to sleep at night.

It means Eva, who has a 4-year-old brother named Albie, is behind her peers at school.

Carla and husband Adam launched charity Eva’s Friends to help children with unknown neurological conditions.

This included a "One in 20,000" fundraiser. Their goal is to raise £2 a month from 20,000 donors and will invest the money into research to speed up diagnosis and treat the condition early.

There are 20,000 genes in the genome - and if one is faulty it leads to serious neurological disorders.

“We want to fund research for conditions to help families like ours cope with the stress of not knowing," Turner said. “We want to fund pioneering research which has the potential to change children's lives.”
