Colin Farrell and ex-girlfriend Kim Bordenave petitioned to be co-conservators of their 17-year-old son James, according to a document obtained by Us Weekly. James, who was born in 2003, has been diagnosed with Angelman syndrome (AS) and is “nonverbal and has issues with his fine motor skills, making him unable to properly care for his own physical health and well-being and requiring him to need assistance in preparing food, eating, bathing and clothing himself,” according to the petition. According to the Angelman Syndrome Foundation, the rare genetic disorder that shares symptoms and characteristics with other disorders including autism, cerebral palsy and Prader-Willi syndrome. Caused by a loss of function of the UBE3A gene in the 15th chromosome, people with AS have developmental problems that become noticeable by the age of 6 to 12 months. “Other common signs and symptoms usually appear in early childhood like walking and balance disorders, gastrointestinal issues, seizures and little to no speech,” the Foundation’s website says. “Despite these symptoms, people with Angelman syndrome have an overall happy and excitable demeanor. An individual with AS will light up a room with their smile and laughter.”
