Systematic investigations indicate that some of the recognized psychiatric disorders can be identified among those with mental retardation due to chromosomal abnormalities. We report a psychotic patient with mild mental retardation (intelligence quotient: 68) and minor anomalies that had a chromosomal aberration not previously described in a psychotic patient. Our patient highlights the importance of the cytogenetic study in psychiatric patients with comorbid mental retardation or minor anomalies. In addition, her psychosis symptoms may be helpful to propose a new candidate gene for psychosis.
