Genes associated with fetal structural abnormalities that have been identified in studies. The horizontal column (blue) represents the number of reported pathogenic genes in each study. The vertical column (black) represents the number of reported pathogenic genes in each intersection. An intersection means a group of pathogenic genes that was shared by one, two, or more studies. The black dots linked by black lines indicate the information that pathogenic genes in each intersection are shared by which studies. The gene symbols in some intersections are labeled
