A De Novo Centric Fission of Chromosome 11 in a Patient with Recurrent Miscarriages

The First Case of a Small Supernumerary Marker Chromosome 18 in a Klinefelter Fetus: A Case Report

Small supernumerary marker chromosomes (sSMCs), or markers, are abnormal chromosomal fragments that can be hereditary or de novo. Despite the importance of sSMCs diagnosis, de novo sSMCs are rarely detected during the prenatal diagnosis process. Usually, prenatally diagnosed de novo sSMCs cannot be correlated with a particular phenotype without knowing their chromosomal origin and content; ther...

A de novo Deletion of Chromosome 18p With Persistent Limb Tremor and Difficulty Speaking: A Case Report

The common causes of 18p deletion syndrome are spontaneous errors in the chromosomal structure in the early stages of human embryonic development. In this study, a 29-year-old girl was introduced with the features of deletion of chromosome 18. In addition, GTG banding karyotype revealed that this case had a deletion involving the short arm of chromosome 18. In comparison with the usual phenotyp...

Prenatal Diagnosis of Mosaic Tetrasomy 18p in a Case without Sonographic Abnormalities

Small supernumerary marker chromosomes (sSMC) are still a major problem in clinical cytogenetics as they cannot be identified or characterized unambiguously by conventional cytogenetics alone. On the other hand, and perhaps more importantly in prenatal settings, there is a challenging situation for counseling how to predict the risk for an abnormal phenotype, especially in cases with a de novo ...

P-75: The Association of Antiphospholipid Syndrome and Recurrent Miscarriages

a:4:{s:10:"Background";s:364:"Antiphospholipid syndrome is a coagulation disorder that causes recurrent miscarriages and fetal deaths. In the present review we summarize current knowledge about Antiphospholipid syndrome that associated with recurrent miscarriages. In addition, on the basis of these comprehensive data, possible pathophysiologic mechanisms of this disorder are discussed.";s:19:"M...
