Purpose: The objective of present study was to know the contribution of different types chromosomal anomalies in manifestation of Turner syndrome. Turner syndrome is a chromosomal disorder mainly due to growth retardation and primary amenorrhoea. Cytogenetic analysis of cases referred for Turner syndrome is necessary for an early diagnosis which helps in genetic counselling to manage it in a better way. Total 23 Methods: 7 cases suspected for Turner syndrome, were included in this study for duration of 7 years (2007-2014). We implemented the standard protocol for peripheral whole blood lymphocyte culture, chromosome preparation followed by G-banding. Chromosomes were analysed according to the guidelines of International System for Human Cytogenetic Nomenclature (2005). Afte Results: r analysing 237 registered cases, chromosomal anomalies were seen only in 47 cases (19.8%). Careful clinical examination of patients with abnormal karyotype (n=47) revealed four major phenotypes i.e. growth retardation (n=19, 40.4%), primary amenorrhoea (n=19, 40.4%), primary amenorrhoea with growth retardation (n=6, 12.8%), and oligoamenorrhoea (n=3, 6.4%). Seven different types of chromosomal abnormalities were observed viz. Monosomy X (n=22, 46.8%), triple X syndrome (n=2, 4.2%), turner mosaic (n=3, 6.4%), ring chromosome (n=5, 10.6%), structural abnormalities with X chromosome (n=6, 12.8%), mosaic structural X abnormality (n=1, 2.1%), XY gonadal dysgenesis (n=8, 17%). This st Conclusion: udy revealed the frequency of most common clinical phenotype and different chromosomal abnormalities in patients suspected for turner syndrome. We observed growth retardation and primary amenorrhoea as most common clinical feature and monosomy of X chromosome as most frequent chromosomal abnormality in this cohort of study.
