A three-year-old boy suffers from a rare genetic disorder which has caused his leg to swell to four times its normal size.

Akshaj Khandelwal has Klippel-Trenaunay Syndrome (KTS) – which affects one in 100,000 people and prevents him from walking normally.

The condition also causes his leg to bleed if he tries to walk more than a few steps and prevents him from going to school on his own.

Unaware of it being a medical condition, the toddler just believes his larger leg is a gift and he is lucky to have it.

People often maintain a distance from him out of fear of being infected – leaving his family scared he will get bullied by other children as he grows older.

But his worried father Ankur, from Delhi, India, believes he is still too young to be told the reality of his condition – for which there is no cure.

Mr Khandelwal said: ‘My son doesn’t know what the condition is. We don’t want to make him feel bad.

‘He believes having a big leg makes him a superman. He is too young to know his problems.

‘He cannot go to school on his own. It’s a very challenging thing to send him to the school.

‘Before joining the school we had to make sure how he would explain his condition to his friends.
