Abstract
Cooperation between a pediatrician and genetics is currently a prerequisite for the reliable diagnosis of many childhood diseases. The aim of the article is to provide a set of basic information that should facilitate the communication of pediatricians with genetic workplaces, and at the same time to outline the meaning of basic genetic examinations.
Since the two papers in this issue are devoted to molecular biology, we focus mainly on cytogenetic and molecular cytogenetic methods. The following text is designed as a set of questions and answers defining individual topics.
