Chromosome 11, Partial Trisomy 11q is a rare chromosomal disorder in which the end (distal) portion of the long arm (q) of the 11th chromosome appears three times (trisomy) rather than twice in cells of the body. Although associated symptoms and findings may vary, the disorder is often associated with delayed growth before and after birth (prenatal and postnatal growth retardation); varying degrees of mental retardation; distinctive abnormalities of the skull and facial (craniofacial) region; and/or other features. Chromosomal analysis is necessary for a definite diagnosis.
(Please note that some of these organizations may provide information concerning certain conditions potentially associated with this disorder [e.g., mental retardation, craniofacial abnormalities, congenital heart defects, etc.].)
