A Glasgow schoolgirl has died just three years after her sister passed away from the same heart condition.

Taylor Muir, 14, of Shettleston, died after suffering from Long QT syndrome, a condition which claimed the life of her 16-year-old sister Jodie three years ago.

Both were diagnosed with the illness, which in the majority of cases delays the flow of potassium ions out of heart muscle cells.

Tributes have been paid to Taylor online, described as "beautiful inside and out".

Friends have launched a fundraising campaign to raise money to go towards funeral costs for the Eastbank Academy pupil.

An online tribute from her friends said: "Our beautiful angel Taylor Muir passed away in the early hours of this morning, her heart simply stopped beating and the hospital staff could not bring her back.

"Taylor was only 14 and had her full life ahead of her.

"Taylor was not only beautiful inside and out but she was so comical and always made us laugh and smile."

Their mother Laura has worked tirelessly to raise money for a heart screening programme through her charity, the Jodie Muir Memorial Trust.

The aim of the initiative is to raise funds for free heart tests through the Cardiac Risk in the Young (CRY) charity.

When Jodie died, it had initially been thought the youngster had taken an ecstasy-type drug.

But her post-mortem examination was inconclusive and a further toxicology report was clean.

It was then it was thought Jodie suffered a "sudden death" due to her underlying heart condition.

Taylor's friends added: "To lose one child is devastating but to lose two is utterly cruel and heartbreaking.

"This fund has been set up to help our friends Laura and Peter so they can give Taylor the send off she truly deserves."

Laura recently won a most caring hero award at a Glasgow community awards ceremony.

The tribute added: "I know Laura will not like us setting up this page as she works so hard to do everything by herself but we are sorry Laura, this time you deserve to have some help.

"You are our true caring hero and we will help you through this."
