Balanced Chromosomal Translocation of Chromosomes 6 and 7: A Rare Male Factor of Spontaneous Abortions
Abstract
Background: Carriers of structural chromosomal rearrangements such as Robertsonian or reciprocal translocations have an increased risk of spontaneous abortion and producing offspring with genetic abnormalities. Case Report: We report a man with balanced chromosomal translocations located at 6p22, and 7q22. His wife has a history of four spontaneous abortions. Conclusion: Couples with a history of abortions should be investigated cytogenetically, after other causes of miscarriages are excluded. The possibility of spontaneous abortions can be reduced with preimplantation genetic diagnosis (PGD) before embryo transfer. Turkish Başlık: Kromozom 6 ve 7'nin Dengeli Koromozomal Yer Değiştirmesi: Spontan Düşüklerin Nadir Bir Erkek Faktörü Anahtar Kelimeler: Dengeli kromozomal yer değiştirme, spontan düşükler, implantasyon öncesi genetik tanı Arka Plan: Robertsonian veya karşılıklı (reciprocal) yer değiştirmeler (translokasyonlar) gibi yapısal kromozomal yeniden düzenleme taşıyıcılığı, genetik anormallikler ile döllenme veya spontan düşük için artmış bir riske sahiptir. Olgu Sunumu: 6p22, and 7q22 lokalizasyonlu dengeli kromozomal yerdeğiştirmeleri olan bir erkek bildiriyoruz. Karısının dört spontan düşüğü bulunmaktadır. Sonuç: Düşük öyküsü olan çiftler, düşüğe sebep olabilecek diğer nedenler dışlandıktan sonra sitogenetik olarak araştırılmalıdır. Spontan düşüklerin olasılığı embriyo transferi öncesinde implantasyon öncesi genetik tanı ile azaltılabilmektedir.
