    Klinefelter syndrome (KS) is the most common male sex chromosome aneuploidy, affecting 1 in 450–600 male births.

  • 2

    The classic karyotype for KS is 47,XXY, present in approximately 90% of cases, with the rest being mosaic or higher-grade aneuploidies.

  • 3

    Men with KS have a significantly elevated risk of metabolic syndrome, with a prevalence of 34-44%, compared to about 10% in healthy males.

  • 4

    Metabolic abnormalities in KS can be observed in prepubertal boys, indicating that the chromosomal aneuploidy contributes to this phenotype.

  • 5

    Early diagnosis and a structured, multidisciplinary surveillance strategy are essential for improving long-term outcomes in individuals with KS.
