Background: High Resolution Melting (HRM) Analysis is a validated, robust, low-cost, high throughput CF screening method. Here, we report the development and retrospective evaluation of the diagnostic value of a novel multiplex HRM, genotyping and haplotyping method for CF prenatal diagnosis (generic HRM/haplotyping).
Methods: 80 study samples from 20 carrier couples referred for PND (whole blood in EDTA and CVS or amniotic fluid) were genotyped retrospectively using the suggested protocol.
Results: All DNA samples (variable sources, extraction methods and unknown concentrations) were successfully amplified by the 1st and 2nd round PCR. The Se, Sp, NPV and PPV for the generic HRM/haplotyping method are calculated at 100%.
Conclusions: This generic protocol for PND using HRM, facilitates the simultaneous analysis of DNA samples from various sources in a fast, robust and efficient way. It can be easily adapted and applied for any genetic condition.

Background: Skeletal dysplasia (SD) represents a series of highly heterogeneous congenital genetic diseases affecting the human skeletal system. Refined genetic diagnosis is helpful for the accurate diagnosis and prognosis evaluation of SDs.
Materials And Methods: In this study, we recruited 26 cases of SD and analyzed them with a designed sequential genetic detection.

Prenatal diagnosis is a crucial tool in reducing birth defects. Research indicates that whole-exome sequencing (WES) is particularly effective for detecting abnormalities associated with structural ultrasound findings. This study aimed to evaluate the utility of WES in the genetic diagnosis of prenatal ultrasound abnormalities.

Background: Current guidelines for screening glucose dysregulation (GD) in patients with transfusion-dependent thalassemia (TDT) recommend an annual 2-hour oral glucose tolerance test (OGTT) starting at the age of 10 years.
Objective: Assessment of adherence to OGTT screening in patients with TDT.
Methods: A questionnaire was distributed to 18 Thalassemia Centers in 10 different countries, targeting factors influencing adherence to annual OGTT screening in specialized multidisciplinary pediatric and adult TDT units and identifying strategies to improve adherence to OGTT in TDT patients.

Background: Hepatocellular carcinoma (HCC) is a ubiquitous malignancy linked to significant mortality. The abnormal expression of β-1,4-N-acetyl-galactosaminyltransferase 1 (B4GALNT1) seemed to be implicated in tumorigenesis. Nonetheless, this enzyme's roles in HCC are unclear.

Parents of children with Down syndrome have historically reported poor experiences receiving a prenatal diagnosis. In a 2003 survey, mothers reported that their physicians pitied them, emphasized negative aspects of Down syndrome, and encouraged them to terminate the pregnancy. This study assesses whether parents' perceptions have since improved.
