- Congenital Abnormality
Clubfoot is a congenital limb deformity defined as fixation of the foot in cavus, adductus, varus, and equinus (i.e., inclined inwards, axially rotated outwards, and pointing downwards) with concomitant soft tissue abnormalities (Cardy et al., 2007). Clubfoot may occur in isolation or as part of a syndrome (e.g., diastrophic dysplasia, 222600). Clubfoot has been reported with deficiency of long bones and mirror-image polydactyly (Gurnett et al., 2008; Klopocki et al., 2012).

Patent ductus arteriosus- MedGen UID:
- 4415
- •Concept ID:
- C0013274
- •
- Congenital Abnormality
In utero, the ductus arteriosus (DA) serves to divert ventricular output away from the lungs and toward the placenta by connecting the main pulmonary artery to the descending aorta. A patent ductus arteriosus (PDA) in the first 3 days of life is a physiologic shunt in healthy term and preterm newborn infants, and normally is substantially closed within about 24 hours after bith and completely closed after about three weeks. Failure of physiologcal closure is referred to a persistent or patent ductus arteriosus (PDA). Depending on the degree of left-to-right shunting, PDA can have clinical consequences.

Bicuspid aortic valve- MedGen UID:
- 57436
- •Concept ID:
- C0149630
- •
- Congenital Abnormality
Bicuspid, or bicommissural, aortic valve (BAV) describes an aortic valve with 2 rather than 3 leaflets (Cripe et al., 2004). In 1 to 2% of the population a bicuspid aortic valve is present. Bicuspid aortic valve is frequently an antecedent to aortic valve stenosis or insufficiency. In extreme cases the blood flow may be so restricted that the left ventricle fails to grow, resulting in hypoplastic left heart syndrome (241550) (Garg et al., 2005). The valve calcification often observed in bicuspid aortic valve is a result of inappropriate activation of osteoblast-specific gene expression. Mutations in the signaling and transcription regulator NOTCH1 cause a spectrum of developmental aortic valve anomalies and severe valve calcification in nonsyndromic autosomal dominant human pedigrees.
Genetic Heterogeneity of Aortic Valve Disease
Also see AOVD2 (614823), caused by mutation in the SMAD6 gene (602931) on chromosome 15q22, and AOVD3 (618496), caused by mutation in the ROBO4 gene (607528) on chromosome 11q24. There is evidence for additional genetic heterogeneity (see MAPPING).

Ductus arteriosus aneurysm (DAA) is a saccular dilatation of the ductus arteriosus. DAA can be either congenital or acquired (e.g. as a complication of surgical closure of a patent ductus arteriosus). Although the majority of patients with congenital DAA are asymptomatic and have a benign course, severe complications, such as rupture or thromboembolism, can occur. DAA is likely to emerge in the third trimester from the aortic junction of the DA, extending towards its pulmonary end.
