TWO young brothers' lives have been transformed after being diagnosed and treated for a rare genetic condition.

Xander Tattersall, seven, and his brother Max, four, from Gawber, have homocystinuria, a condition which affects the nervous system and can lead to blood clots and osteoporosis.

Having both experienced learning and behavioural difficulties, the family often stayed at home as going out in public was so stressful because of the boys becoming upset and stressed.

But life has been changing in the last six months since they were referred to Sheffield Children's Hospital and diagnosed with a rare genetic disease by Dr Sufin Yap, a consultant in metabolic diseases.

The boys' mum Sophia Tattersall, 34, said: "I was so relieved to find out there was an actual reason for the difficulties the boys have been having.

"Xander is now learning really well and starting to make significant steps and although Max has been quite poorly as he has epilepsy as well, we are really getting there now."
