Abstract:
We present the first case of CTNND1 variant with a prenatal clinical phenotype of total anomalous pulmonary venous connection. The genetic analysis identified a heterozygous pathogenic variant NM_001085458.2: c.2098C>T (p.R700*) in the CTNND1 gene of the fetus. This case expands the phenotypic spectrum of CTNND1 gene, provides a novel clinical reference for prenatal diagnosis, and suggests that the CTNND1 gene plays a crucial role in early cardiac development.

Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Overview of Systemic Veins
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the middle...

CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...
