Summary

A patient with a deletion of the distal portion of the long arm (q21) of chromosome Y is described clinically and cytogenetically. The proband has a normal male habitus but with azoospermia.

The proband was investigated because of infertility. Male relatives were also investigated cytogenetically. The deleted Y chromosome was measured and compared with the normal Y of male family members. The results suggest that no Y euchromatin was lost.
