Actor Colin Farrell, best known for “Miami Vice” and “S.W.A.T.,” confessed that his first son James, who has Angelman syndrome, inspired him to become sober. Advertisement According to the Mayo Clinic, Angelman syndrome is a genetic disorder that causes delayed development, problems with speech and balance, and intellectual disability.

“ [ James] is an absolute stud,” Colin Farrell told PEOPLE of his son while attending the Winter’s Tale premiere in New York City on Tuesday. James — who is the actor’s son with model Kim Bordenave — lives with Angelman Syndrome, a rare genetic disorder that is known to impair speech, movement and balance.

He was born with a rare genetic disorder called Angelman syndrome, a developmental disability, characterized by seizures, jerky movements and sleeping problems. There is no known cure.

Colin Farrell has filed for conservatorship of his 17-year-old son, James Farrell, who has been diagnosed with Angelman Syndrome. According to the court petition obtained by E! News, Colin and model Kim Bordenave, who is James' mother, are requesting to be co-conservators of his person in a limited conservatorship.

For the most part, as is the case with Farrell and Bordenave, the parents do not have the condition. It occurs because of a genetic difference that usually happens when the gene known as UBE3A is either missing or not working properly.
