Double Aneuploidy

The article represents the double aneuploidy, a rare form of chromosome pathology. 6 cases of double aneuploidy were diagnosed prenatally and 1 case was diagnosed postnatal. A variety of ultrasound signs is shown in this chromosomal pathology. The prevalence of phenotypic features of the chromosomal disease, which has the greatest clinical manifestation, was noted.

Phenotypic Features

The case of a 63-year-old severely mentally handicapped man is reported with chromosomal mosaicism. His karyotype was established as mosaic 46XY/47XXY with the fragile site present in a proportion of cells of both cell-lines. He showed phenotypic features which could be related both to the fragile-X and Klinefelter's syndromes.

AbstractLabeling clinical data from electronic health records (EHR) in health systems requires extensive knowledge of human expert, and painstaking review by clinicians. Furthermore, existing phenotyping algorithms are not uniformly applied across large datasets and can suffer from inconsistencies in case definitions across different algorithms. We describe here quantitative disease risk scores based on almost unsupervised methods that require minimal input from clinicians, can be applied to large datasets, and alleviate some of the main weaknesses of existing phenotyping algorithms. We show applications to phenotypic data on approximately 100,000 individuals in eMERGE, and focus on several complex diseases, including Chronic Kidney Disease, Coronary Artery Disease, Type 2 Diabetes, Heart Failure, and a few others. We demonstrate that relative to existing approaches, the proposed methods have higher prediction accuracy, can better identify phenotypic features relevant to the disease under consideration, can perform better at clinical risk stratification, and can identify undiagnosed cases based on phenotypic features available in the EHR. Using genetic data from the eMERGE-seq panel that includes sequencing data for 109 genes on 21,363 individuals from multiple ethnicities, we also show how the new quantitative disease risk scores help improve the power of genetic association studies relative to the standard use of disease phenotypes. The results demonstrate the effectiveness of quantitative disease risk scores derived from rich phenotypic EHR databases to provide a more meaningful characterization of clinical risk for diseases of interest beyond the prevalent binary (case-control) classification.
