Molecular analysis of a large novel deletion causing α+-thalassemia

BMC Medical Genetics, 2019
Background α-thalassaemia is an inherited blood disorder caused by mutations in the α-globin gene cluster. Recognizing the pathogenic α-globin gene mutations associated with α-Thalassemia is of significant importance to thalassaemia’s diagnosis and ...

Synthesis of realistic fetal MRI with conditional Generative Adversarial Networks [PDF]

arXiv, 2022
Fetal brain magnetic resonance imaging serves as an emerging modality for prenatal counseling and diagnosis in disorders affecting the brain. Machine learning based segmentation plays an important role in the quantification of brain development. However, a limiting factor is the lack of sufficiently large, labeled training data.

Nanopore Sequencing Solves an Elusive Case of Sotos Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Sotos syndrome is a rare genetic disorder characterized by distinctive facial features, including a broad and prominent forehead, dolichocephaly, and learning disabilities ranging from mild to severe intellectual impairment. Affected individuals often show overgrowth in height and head circumference over two standard deviations.

Deep-learning models improve on community-level diagnosis for common congenital heart disease lesions [PDF]

arXiv, 2018
Prenatal diagnosis of tetralogy of Fallot (TOF) and hypoplastic left heart syndrome (HLHS), two serious congenital heart defects, improves outcomes and can in some cases facilitate in utero interventions. In practice, however, the fetal diagnosis rate for these lesions is only 30-50 percent in community settings. Improving fetal diagnosis of congenital

Automatic Detection of Cardiac Chambers Using an Attention-based YOLOv4 Framework from Four-chamber View of Fetal Echocardiography [PDF]

arXiv, 2020
Echocardiography is a powerful prenatal examination tool for early diagnosis of fetal congenital heart diseases (CHDs). The four-chamber (FC) view is a crucial and easily accessible ultrasound (US) image among echocardiography images. Automatic analysis of FC views contributes significantly to the early diagnosis of CHDs.

Neonatally Lethal Fanconi Anemia due to an Amish Founder FANCE Gene Variant; Evidence for Genotype–Phenotype Correlation

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Prenatal and neonatal presentations of multiple congenital anomalies are difficult to diagnose and are associated with an increased risk of lethality. The differential diagnosis of antenatal presentations of radial ray malformations includes Fanconi anemia (FA), an inherited bone marrow failure disorder associated with congenital anomalies in ...

Health disparities in chronic liver disease

Hepatology, EarlyView., 2022
Abstract The syndemic of hazardous alcohol consumption, opioid use, and obesity has led to important changes in liver disease epidemiology that have exacerbated health disparities. Health disparities occur when plausibly avoidable health differences are experienced by socially disadvantaged populations.

Detection of contamination in noninvasive prenatal fetal gender test [PDF]

arXiv, 2015
The risk of false positive results in noninvasive prenatal diagnosis focused on fetal gender and RhD status determination could be a problem in clinical routine. This is because these tests are based on detection of presence of DNA sequences with high population frequency and so there is the risk of sample contamination during sample collection and ...
