Pulmonary valve agenesis-tetralogy of Fallot-absence of ductus arteriosus syndrome is a rare congenital heart malformation characterized by a tetralogy of Fallot (pulmonary stenosis, overriding aorta, ventricular septal defect and right ventricular hypertrophy), complete absence or rudimentary pulmonary valve that is both stenotic and regurgitant and an absence of the ductus arteriosus. It presents prenatally with cardiomegaly, polyhydramnios, fetal heart failure, hydrops fetalis and fetal demise or postnatally with cyanosis and respiratory failure due to bronchomalacia secondary to bronchial compression from dilated pulmonary arteries. It is frequently associated with 22q11 deletion. |

Curry-Jones syndrome is a form of syndromic craniosynostosis characterized by unilateral coronal craniosynostosis or multiple suture synostosis associated with complete or partial agenesis of the corpus callosum, preaxial polysyndactyly and syndactyly of hands and/or feet, along with anomalies of the skin (characteristic pearly white areas that become scarred and atrophic, abnormal hair growth around the eyes and/or cheeks, and on the limbs), eyes (iris colobomas, microphthalmia,) and intestine (congenital short gut, malrotation, dysmotility, chronic constipation, bleeding and myofibromas). Developmental delay and variable degrees of intellectual disability may also be observed. Multiple intra-abdominal smooth muscle hamartomas, trichoblastoma of the skin, occipital meningoceles and development of desmoplastic medulloblastoma have been reported. |
