Molecular cytogenetic analysis of multi-miscarriage products of conception in clinical cases from Al-Anbar Governorate, west of Iraq

Abstract

Most clinical miscarriages often occur throughout the first trimester of pregnancy, with fetal chromosomal abnormalities being identified as the primary reason for such occurrences. The objective is to analyze the fetal chromosomal aberrations in the product of conception among Iraqi patients suffering from recurrent miscarriages. The cross-sectional study was performed on 60 cases of products of conception in women suffering from multiple miscarriages, obtained from Department of Obstetrics and Gynecology is located in Ramadi Teaching Hospital for Child and Maternity, as well as other Private Clinics in the Ramadi City. Long-term culture of conventional cytogenetic analysis using the G-banding technique was employed to determine the chromosomal disorder of fetal tissue part or villus samples. Fetal chromosomal abnormalities were detected in 86.7 %. Numerical chromosomal abnormalities were revealed in 98.1 %, while structural abnormalities were detected in 1.9 %. Additionally, the commonest gestation loss occurs in parents under 35 years in the first trimester (92.3 %). Trisomy 21 was the most frequent (46.2 %) in gestational loss. Fetal chromosomal abnormalities have been linked with gestational loss in Iraqi couples. Therefore, it is recommended that cytogenetic analysis should be performed to identify the genetic cause of recurrent miscarriage. This is important for providing appropriate genetic counseling and educating couples about the risk of future pregnancies.
