Partial 4q duplication due to inherited der(20), t(4;20)(q25;q13)mat
Ann Genet.
1977 Mar.
Abstract
A boy with mental and growth retardation associated with congenital anomalies has a partial duplication of the distal 4q chromosome region as a result of inheritance of a t(4:20) from his mother. Comparison with twelve other patients from the literature indicates that similar clinical features may be associated with this chromosome change suggesting a partial 4q duplication syndrome.
