A SCHOOLGIRL with a rare genetic disorder will be treated like royalty when she opens Santa's grotto at Sanders Garden World in Brent Knoll on Saturday.

Mia Marshall, seven, from Mark, was plucked from dozens of entries to cut the ribbon.

The East Brent First School pupil was born with Turner Syndrome, a disorder that only affects girls and means a number of X chromosomes are missing.

It causes physical problems such as short stature, puffy hands and feet, heart problems, high blood pressure, visual impairments and hearing difficulties.

Pony lover Mia must have growth hormone treatments to ensure that she continues to develop.

Her mum Libby explained: “She is such a happy little girl, despite needing daily injections and ongoing operations.

“Mia never lets her condition get her down and even though she often has to spend time in hospital, she doesn't complain at all.

“She was really excited to hear that she has been chosen to open Santa's grotto at Sanders Garden World.”

Mia will be awarded with a free pass for four people to the Winter Wonderland and four free passes to visit Santa in his grotto.

Peter Burks, Sanders manager, said: “Mia is clearly a deserving winner. She has overcome some considerable health-related challenges and her positive outlook has really impressed us.”

Four runners up, Alex Harvey from Highbridge, Maddie Hilyer, from Berrow, Elliott Edwards, and Katie Rendell, both from Burnham, will also each receive four free entry passes to Santa's grotto.
