Trisomy 8q

A partial autosomal trisomy characterized by developmental delay, intellectual disability, prenatal and postnatal growth retardation, congenital heart, genitourinary and skeletal anomalies, and dysmorphic facial features, including high and broad forehead, hypertelorism, upslanting palpebral fissures, broad nose, dysplastic and low set ears, micrognathia. Phenotypic features vary in relation to the duplication size.
