Abstract
TGK (Tekrarlayan Gebelik Kaybı) etiyolojisinde rol oynayan
faktörlerin % 50’si genetiktir. Resiprokal translokasyonlar kromozomal yeniden
düzenlenmelerdir. Dengeli resiprokal translokasyon taşıyıcıları % 50 oranında
dengesiz genetik materyal içeren gametler oluşturmakta ve bu durum TGK’ ya veya
konjenital anomalilere neden olmaktadır. TGK öyküsü ile Mersin Üniversitesi
Hastanesi üroloji kliniğine başvuran probandın eşinde 8. haftada embriyonik
gelişimin durması nedeniyle dört küretaj öyküsü vardı, bir sağlıklı çocuğa
sahipti. Laboratuvarımıza yönlendirilen hastanın pedigrisi alındıktan sonra
sitogenetik analizi yapıldı. Probandın
46,XY,t(10;17)(p13;q22) dengeli resiprokal translokasyon taşıyıcısı olduğu
tespit edildi. Translokasyona uğrayan 17q22àqter bölgesinde proteine kodlanan 606 gen bulunmaktadır.
Bunlardan bazıları, CDK3 (Cyclin-Dependent Kinase 3; Cell Division Kinase 3), GAA (Gluosidase, Alpha, Acid) ve GRB2 (Growth
Factor Receptor- Bound Protein 2) gibi embriyonik gelişimde ve hücre
metabolizmasında önemli rol oynayan genlerdir. Probandın gametlerine dengesiz
genetik materyal aktarılması durumunda embriyo bu bölgede kodlanan genler
açısından monozomik veya trizomik olacaktır. Bu durumda embriyo gelişimi
durmakta ve gebelik abortus ile sonuçlanmaktadır.

Abstract
50% of the genetic factors that play a role in the etiology of
Recurrent Pregnancy Loss (RPL). Reciprocal translocations are chromosomal
rearrangements. Balanced reciprocal translocation carriers produce gametes
containing 50% of unstable genetic material, leading to RPL or congenital
anomalies. Proband who admitted to Mersin University Hospital Urology Clinic
with a history of RPL in his wife. She has four curettage histories due to
cessation of embryonic development at 8 weeks. Also they have one healthy
child. Cytogenetic analysis was performed after pedigree of the
patient who was referred to our laboratory. Proband 46, XY, t (10; 17) (p13;
q22) was found to be a balanced reciprocal translocation carrier. There are 606
genes encoded into the protein in the 17q22àqter region that has been translocated. Some of these are
genes that play an important role in embryonic development and cell metabolism
such as CDK3 (Cyclin-Dependent Kinase 3; Cell Division Kinase 3), GAA (Gluosidase, Alpha, Acid) and GRB2 (Growth Factor
Receptor- Bound Protein 2). If
unbalanced genetic material is transferred to the gametes of the probe, the
embryo will be monosomic or trisomic for the genes encoded in this region. In
this case, embryo development stops and pregnancy results in abortion.
