Klinefelter Syndrome - Cytogenetic Findings

In this article it if reported that the karyotype variants in the cytogenetically confirmed sixty four Klinefelter Syndrome patients. Forty had the 47. XXY karyotype (62.5%). The rest had the following : 48. XXYY 2 (3.13%). 48. XXY + 21 : 2 (3.13%). 46. XX/47, XXY : I (1.56%). 46. XY/47. XXY : 15(23 44%). 46. XY / 48. XXXY : I (1.56%). 47. XXY / 48. XXXY : I (I 56%). 48. XXXY / 49. XXXXY : I (1.56%) The only structural arrangement observed was 47. XXYqh+. The observations of the present study confirm the karyotypic variability in Klinefelter syndrome
