Yq deletion, aspermia, and short stature

摘要

A large Yq deletion involving both the fluorescent and part of the non-fluorescent segment in a 36-year-old phenotypic normal male is presented. His short stature and aspermia gives strong support, after a complete review of the literature, to the existence of factors involved in the control of both characteristics in the non-fluorescent segment of the long arm of chromosome Y, distally within band 11.
