Duplication 6q21q23 in two unrelated patients.

We report on two patients with rare 6q duplications. The karyotype of patient 1 is 46,XY,dup(6)(q21q23.3). The karyotype of patient 2 is 46,XX,dup(6)(q21.15q23.3). These two patients have some nonspecific physical findings in common including a depressed nasal bridge, epicanthal folds, mild heart defects, and developmental delay, but each had other congenital anomalies.
