Study of Genetic Aberrations of Sex Chromosome for Turner Syndrome in Peripheral

Abstract

In this study we do achromosomal analysis to 26 iraqi patients with confirmed Turner Syndrom , after subjected to medical examination by their doctors. Turner Syndrom is achromosomal abnormalities in X chromosome .the age of pateins are among (5-25) years old and divided into tow groups ,the first one is patients with age below 12 years old and the second is patients with age above 12 years old.
The goal of this study is to understand the major causes of increase the genetic disorders in Iraq .The results showed in group one founds normal genetic structure in all examined cells,but in group tow its found eight case from twenty one case had Turner Syndrom ,due to the absence of one of the X chromosome ,under chromosomal profilic (45X0). And (Xp-,Xq-,iX) with variation in its frequency between patients . The conclusion was increase in chromosom changes due to several factors such as pollutions.
