objective: approximately 15-20% of clinically recognizable pregnancies end in spontaneous abortion. the incidence of chromosomal abnormalities in those abortions is as high as 50%.a modest but clinically important proportion of spontaneous abortions is caused by a balanced chromosomal aberration in one of the parents. this results from the production of gametes and embryos with unbalanced chrom...

one of the major causes of spontaneous abortion before the fourth month of pregnancy is chromosomal abnormalities. we report an unusual case of a familial balanced chromosomal translocation in a consanguineous couple who experienced 4 spontaneous abortions. chromosomal studies were performed on the basis of g-banding technique at high resolution and revealed 46, xx, t (16 6) (p12 q26) and 46, x...

background: approximately 205 million pregnancies occur each year in the worldwide. on the other hand, spontaneous abortion has been reported in 15-20% of all diagnosed pregnancies. the most common cause of spontaneous abortion is chromosomal abnormalities of the embryo. robertsonian translocation carriers specially 21-14 are the most common balanced rearrangement among the carrier couples with...

background: recurrent abortion is a difficult medical problem happening in about 1-2% of fertile women. most spontaneous miscarriages which happen in the first and second trimesters are caused by chromosomal abnormalities. objective: the present study tries to find the rate of chromosomal abnormalities in couples with recurrent pregnancy loss. materials and methods: in total 165 couples were re...

background and objective: failure to thrive (ftt) is a sign that describes a particular problem rather than a diagnosis and explain growth failure or more advanced failure to gain weight appropriately. the aim of this study was to determine the prevalence and type of chromosomal abnormalities in patients presented with ftt. materials and method: one hundred ftt cases with clinical impression o...
