'Giant', 22, stands at 7ft 9in tall after not being expected to live past his ...

A man who measures an astonishing 7ft 9ins has landed his dream job working at a sports centre.

Broc Brown, from Michigan, was once crowned the 'world's tallest teen'. He was not expected to make it past adolescence.

The now 22-year-old was born with Sotos syndrome, a genetic disorder also known as cerebral gigantism.

Mr Brown, who was 5ft 2ins at nursery, has always needed custom-made clothing and even sleeps in an 8ft-long bed.  

His abnormally large BMI has caused him to develop diabetes, while his imposing stance means he struggles to walk. 

Mr Brown has finally realised his life-long dream of working at a YMCA sports centre and hopes to one day open his own restaurant.

Mr Brown was diagnosed with Sotos syndrome when he was just five years old, after doctors noticed he was towering over his peers. 

As a teenager, Mr Brown grew at an astonishing rate of 6ins a year and was 7ft throughout secondary school. 

His mother Darci previously said: 'It's a genetic disorder and there's nothing that can stop him from growing - I don't know if he will ever stop.'

Although he defied the odds to survive, Mr Brown was recently diagnosed with diabetes, which doctors have put down to his height.

WHAT IS SOTOS SYNDROME? 

Sotos syndrome is a genetic condition that causes 'overgrowth', leaving patients 'significantly taller' than their peers.

It is reported in one in every 10,000-to-14,000 newborns. 

However, many cases are thought to go undiagnosed. 

Sotos is also defined by its characteristic facial features, which include a long, narrow face; high forehead; flushed cheeks; and a small, pointed chin.

Patients tend to be very tall during childhood, however, 'adult height is usually in the normal range'.

Sufferers often have intellectual disabilities, such as ADHD, phobias, obsessions, tantrums and impulsive behaviours.

Speech problems are also common, with many having a stutter or monotone voice.

Curvature of the spine, seizures, hearing loss, and defects of the heart and kidneys can also occur. 

Up to 90 per cent of cases come about due to mutations in the NSD1 gene.

NSD1 controls the activity of other genes that are involved in growth and development. 

Around 95 per cent of cases occur 'randomly', with the remainder being thought to be inherited.

Sotos has no standard course of treatment.

Therapies aim to just control symptoms.

His stance also means he struggles to move or walk long distances.

Sotos syndrome also caused Mr Brown to be born with only one kidney.

This makes his diabetes more difficult to manage, with the condition being the leading cause of kidney disease, according to the National Institute of Diabetes and Digestive and Kidney Diseases. 

Sotos syndrome has also left Mr Brown with learning difficulties, a strain on his heart, curvature of the spine and narrowing of the spinal cord. 

Despite living in near-constant pain, Mr Brown has always aspired to have a job. 

In 2016, he said: 'I dream of working in a sporting goods store when I'm older, hopefully I can make that happen.'

Three years on, Mr Brown spends every Saturday working at the Jackson YMCA sport centre.
