Detection of aneuploidies by paralogous sequence quantification.
BACKGROUND Chromosomal aneuploidies are a common cause of congenital disorders associated with cognitive impairment and multiple dysmorphic features. Pre-natal diagnosis of aneuploidies is most commonly performed by the karyotyping of fetal cells obtained by amniocentesis or chorionic villus sampling, but this method is labour intensive and requires about 14 days to complete. METHODS We have ...
متن کاملextremal region detection guided by maxima of gradient magnitude
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
Sequence and gene expression evolution of paralogous genes in willows
Whole genome duplications (WGD) have had strong impacts on species diversification by triggering evolutionary novelties, however, relatively little is known about the balance between gene loss and forces involved in the retention of duplicated genes originating from a WGD. We analyzed putative Salicoid duplicates in willows, originating from the Salicoid WGD, which took place more than 45 Mya. ...
متن کاملPrenatal detection of fetal aneuploidies using transcervical cell samples.
In the course of an investigation aimed at detecting the presence of trophoblastic cells in the endocervical canal of pregnant women between 7 and 17 weeks of gestation, several cases of aneuploidies were observed using a fluorescent in situ hybridisation (FISH) assay. The cases include fetal chromosome 21 and 18 trisomies, triploidy and sex chromosome aneuploidies. The results were confirmed b...
متن کاملUsing Disease-Associated Coding Sequence Variation to Investigate Functional Compensation by Human Paralogous Proteins
Gene duplication enables the functional diversification in species. It is thought that duplicated genes may be able to compensate if the function of one of the gene copies is disrupted. This possibility is extensively debated with some studies reporting proteome-wide compensation, whereas others suggest functional compensation among only recent gene duplicates or no compensation at all. We repo...
