Review Question - QID 109990

A 16-year-old boy is brought in to a psychiatrist's office by his mother for increasingly concerning erratic behavior. Her son has recently entered a new relationship, and he constantly voices beliefs that his girlfriend is cheating on him. He ended his last relationship after voicing the same beliefs about his last partner. During the visit, the patient reports that these beliefs are justified, since everyone at school is “out to get him.” He says that even his teachers are against him, based on their criticism of his schoolwork. His mother adds that her son has always held grudges against people and has always taken comments very personally. The patient has no psychiatric history and is in otherwise good health. What condition is this patient genetically predisposed for?
