Exploring mosaicism in Klinefelter Syndrome: a detailed analysis of the genetic and clinical aspects of 6 cases
Keywords:
MOSAICISM, KLINEFELTER SYNDROME, HYPOGONADISM.Abstract
Introduction: klinefelter syndrome with mosaicism is a complex genetic variant characterized by the presence of cells with XXY karyotype in certain tissues and XY karyotype in others.
Objective: to deepen the knowledge of mosaicism and Klinefelter's syndrome by means of a clinical case study.
Methods: in order to obtain a complete and updated overview, we present an exhaustive and thorough search in prestigious medical databases, such as PubMed and Web of Science, covering a period between 2019 and 2023. We employed relevant search terms, such as “Mosaicism”, “Klinefelter's syndrome” “Hypogonadism” and “47XXY”.
Results: mosaicism in Klinefelter syndrome may have an impact on clinical presentation and severity of physical features. Some individuals with mosaicism may exhibit less obvious signs of the condition, which may hinder early diagnosis. Characteristic features of Klinefelter syndrome, such as gynecomastia, hypogonadism and short stature, may vary in their intensity depending on the degree of mosaicism present in the cells.
Conclusions: a comprehensive approach to the management of Klinefelter syndrome with mosaicism is important, highlighting the need for early detection and a personalized approach to medical care. This study contributes to a better understanding of this genetic variant and provides valuable information for clinical practice and future research.
