A man with a genetic disorder has said he feels “happy and shocked” after thousands of people on Twitter congratulated him for landing his first job.

Justin G, who did not wish to share his second name, went viral overnight after he tweeted about landing his new position.

“I am in a loss of words and do not know what to say other then lets party,” the 25-year-old from Boston, Massachusetts, wrote in the post, which has more than 24,000 likes.

“This is my first ever job in my whole life I wont let my disability stop me.”

Justin’s role will see him creating social media posts for Charge Across America, a TV docuseries about racing electric vehicles, and he is set to start on Monday or Tuesday next week.

DiGeorge syndrome, also known as 22Q syndrome, is a disorder where part of a person’s 22nd chromosome is missing.

The disorder has a number of symptoms, but for Justin it has given him heart issues and learning difficulties.

“I want to share people with special needs you can a job and you can’t let your disability get in the way,” Justin told the PA news agency.

“I feel so amazing the internet is celebrating my success… I felt so, so, so happy and shocked when I was getting tons of support.

“It made me more confident in myself to keep going and pushing.”

This is not the first time Justin has gone viral – he has received thousands of messages, likes and shares at different times, sometimes when he has asked Twitter users to say hello to him or wish him a happy birthday.

Among a number of celebrities to send him greetings or messages of support are talk show host Ellen DeGeneres, Star Wars actor Mark Hamill and billionaire Mark Cuban.
