A proposed standard system of nomenclature of human mitotic chromosomes

Abstract

RAPID GROWTH of knowledge of human chromosomes in several laboratories, following advances in technical methods, has developed a number of systems by which they are named. This has led to confusion in the literature and so to the need for resolving the differences. Consequently, Dr. C. E. Ford suggested that a study group convene to attempt to formulate a common system of nomenclature. The meeting was held in the University of Colorado, under the auspices of the Medical School with the support of the American Cancer Society. For practical reasons, the group was limited to those human cytologists who had already published karyotypes. In addition, three counselors were invited to guide and aid the discussions and, if necessary, to arbitrate. Fortunately the last proved unnecessary, and it was possible to arrive at a common system with flexibility by mutual agreement.
