Abstract:

A case of a derivative chromosome 7 formed by a ring chromosome 7 and t(7;9) was found who presented with dimorphic anaemia with no other anomaly. Ring chromosome 7 was characterized by conventional and molecular cytogenetic techniques.

Partial G-banded karyotypes shows normal and abnormal ring chromosome 7
