The Value of Parental Karyotyping in Recurrent Pregnancy Loss Lies in Individual Risk Assessments.

Recurrent pregnancy loss (RPL) is a multifactorial condition, encompassing genetic, anatomical, immunological, endocrine, as well as infectious and environmental factors; however, the etiology remains elusive in a substantial number of cases. Genetic factors linked to RPL include parental karyotype abnormalities (e.g.

Cytogenetic Analysis of Sporadic First-Trimester Miscarriage Specimens Using Karyotyping and QF-PCR: A Retrospective Romanian Cohort Study.

It is well known that first-trimester miscarriages are associated with chromosome abnormalities, with numerical chromosome abnormalities being the ones most commonly detected. Conventional karyotyping is still considered the gold standard in the analysis of products of conception, despite the extended use of molecular genetic techniques. However, conventional karyotyping is a laborious and time-consuming method, with a limited resolution of 5-10 Mb and hampered by maternal cell contamination and culture failure.

Expanding the Clinical Phenotype of 19q Interstitial Deletions: A New Case with 19q13.32-q13.33 Deletion and Short Review of the Literature.

19q13 microdeletion syndrome is a very rare genetic disease characterized by pre- and postnatal growth retardation, intellectual disability, expressive language impairment, ectodermal dysplasia, and slender habitus. Since the description of the first case in 1998, less than 30 cases have been reported worldwide. This article aims to review the knowledge gathered so far on this subject and to present the case of a 10-year-old girl admitted to the National University Center for Children Neurorehabilitation "Dr.

The Phenotypic Spectrum of 15q13.3 Region Duplications: Report of 5 Patients.

Chromosome 15q13.3 microduplications are associated with a wide spectrum of clinical presentations ranging from normal to different neuropsychiatric conditions, such as developmental delay (DD), intellectual disability (ID), epilepsy, hypotonia, autism spectrum disorders (ASD), attention-deficit hyperactivity disorder, and schizophrenia. The smallest region of overlap for 15q13.

Prenatal diagnosis of a pure 15q distal trisomy derived from a maternal pericentric inversion: A case report.

Distal trisomy or duplication of 15q is a very rare chromosomal disorder; most of the previously reported cases were derived from unbalanced translocations involving chromosome 15 and another chromosome, whereas other mechanisms (e.g. duplication) have rarely been reported.

Determination of autophagy gene ATG16L1 polymorphism in human colorectal cancer.

Autophagy has emerged not only as an essential repair mechanism to degrade damaged organelles and proteins but also as a major player in protection of tumor cells from multiple stresses. It was shown that autophagy gene polymorphisms are correlated with development of chronic inflammatory lesions, which represent a risk factor for colorectal tumors. In this study, we aimed to determine if ATG16L1 +898A>G (Thr300Ala) polymorphism is associated with an increased risk of developing colorectal cancer (CRC) and to establish correlations between ATG16L1 genotypes and the major clinical and morphological parameters.
