M. Balkan, Akbas, H., İsi, H., İsi, H., Oral, D., Turkyılmaz, A., Kalkanli, S., Simsek, S., Fidanboy, M., Alp, M. N., Gedik, A., and Budak, T., Cytogenetic analysis of 4216 patients referred for suspected chromosomal abnormalities in Southeast Turkey, vol. 9, pp. 1094-1103, 2010.

We reviewed cytogenetic studies performed on 4216 patients who were referred to the Cytogenetics Unit at Dicle University Hospital, Diyarbair, Southeast Turkey, between 2000 and 2009. The cases were grouped according to the reason of referral for cytogenetic analysis. The frequencies of the different types of numerical and structural abnormalities were determined, and the relative frequency of cases with abnormal karyotypes was calculated in each group. The most common reason for requesting cytogenetic testing was referral for Down syndrome and for repeated abortions.
