Aims: Recurrent abortions comprise almost 15% of diagnosed pregnancies. Chromosomal inversions, as a type of chromosomal rearrangements can result in abortion or the birth of abnormal neonates. The aim of this study was to evaluate the prevalence of chromosome inversions (pericentric and paracentric) in patients with recurrent abortions.
Materials & Methods: This descriptive study was conducted on 2299 couples with recurrent abortions referred to Sarem women’s hospital (Tehran, Iran) during 2006 to 2014. The structure of autosomal and sex chromosomes were studied using high resolution GTG banding and C banding techniques.
Findings: In total, 49 (2.1%) patients showed chromosomal inversions. Pericentric inversion around centromere of chromosome 9 (p11.2q13) was observed in 29 patients (1.26%). Chromosomal inversions were found in heterochromatin region of chromosome 1 in one patient and chromosome Y in one other patient. Pericentric inversion of chromosome 2 was also found in one patient. Chromosomal inversion involving other autosomal chromosomes included pericentric inversion of chromosomes 1, 5, 8, 11 and 12, and paracentric inversion of chromosomes 3, 6, 7, 8, and 12 (0.44%).
Conclusion: The prevalence of pericentric and paracentric chromosomal inversions in patients with abortion history is 2.1%. The rate of pericentric inversions of chromosome 9 in p11.2q13regions is 1.26% that is similar to the normal populations and it has no clinical significance.
