Article Abstract
Over 60% of single-gene diseases in newborns are autosomal dominant variants. Noninvasive prenatal testing for monogenic conditions (NIPT-SGG) is cost-effective and timesaving, but not widely applied. This study introduces and validates NIPT-SGG in detecting 25 monogenic conditions. NIPT-SGG with a 30-gene panel applied next-generation sequencing and trio assays to confirm variants. Diagnostic tests confirmed NIPT-detected cases. Among 93 pregnancies with ultrasound findings, 11 (11.8%) fetuses were screened and diagnosed with monogenic diseases, mostly with Noonan syndrome. NIPT-SGG determined >99.99% of actual positive and negative cases, confirmed by diagnostic tests. No false-negatives or false-positives were reported. NIPT-SGG effectively identifies the fetuses affected with monogenic diseases, which is a promisingly safe and timely antenatal screening option for high-risk pregnancies.

Purpose: To define the genetic architecture of foveal morphology and explore its relevance to foveal hypoplasia (FH), a hallmark of developmental macular disorders.
Methods: We applied deep-learning algorithms to quantify foveal pit depth from central optical coherence tomography (OCT) B-scans in 61,269 UK Biobank participants. A genome-wide association study (GWAS) was conducted using REGENIE, adjusting for age, sex, height, and ancestry.

Background: Polygenic risk scores (PRS) are not yet standard in clinical risk assessments for familial breast cancer in Sweden. This study evaluated the distribution and impact of an established PRS (PRS) in women undergoing clinical sequencing for hereditary breast cancer.
Findings: We integrated PRS into a hereditary breast cancer gene panel used in clinical practice and calculated scores for 262 women.

Sudden cardiac death (SCD) is one of the leading causes of death worldwide. Coronary artery disease (CAD) is the predominant cause of SCD in older individuals, while inherited cardiomyopathies and channelopathies are more common in younger individuals under the age of 35 years. Genetic disorders associated with SCD have traditionally been perceived as monogenic disorders.
