Abstract
Cytogenetics is an essential part of human genetics which studies the structure of chromosomes and their collection which is called karyotype. Cytogenetic techniques are employed while interrogating DNA organisation and compaction. Analysis of the chromosomal structure contributes to uncovering the molecular basis of various cellular processes in normal and pathological conditions. Furthermore, spectrum and frequency of chromosome abnormalities serves as an indicator of mutagenic effects. Cytogenetic techniques became indispensable for discovering the genetic causes of human diseases at different stages of ontogenesis. Genetic abnormalities are a common cause of impaired reproductive function, abnormal pregnancy, and neonatal malformations. Genetic screening for chromosomal abnormalities and congenital anomalies is a powerful tool for reducing the genetic load in human populations as well as disease, psychological and social burden on families and societies. This paper begins the cycle of lectures on molecular basis of human cytogenetics, cytogenetic techniques, and the corresponding research and clinical applications. The lecture is primarily aimed at biomedical students and physicians who often have an unmet need to analyse and interpret the results of cytogenetic analyses.
