General Discussion

Chromosome 11, Partial Monosomy 11q is a rare chromosomal disorder in which a portion of the long arm (q) of chromosome 11 is missing (deleted or monosomic). The range and severity of symptoms may vary, depending upon the exact size and location of the deletion on 11q. Chromosome 11, Partial Monosomy 11q may be characterized by abnormally slow growth before and after birth (prenatal and postnatal growth retardation), mental retardation, and/or moderate to severe delays in the acquisition of skills requiring the coordination of mental and muscular activity (psychomotor retardation). Characteristic physical abnormalities may include malformations of the head and facial (craniofacial) area, abnormalities of the eyes, malformations of the hands and/or feet, and/or defects of the heart. The exact cause of Chromosome 11, Partial Monosomy 11q is not fully understood.
