The primary features are an abnormality in skin development (called aplasia cutis congenita) and malformations of the limbs. A variety of other features can occur in people with Adams-Oliver syndrome. Most people  with Adams-Oliver syndrome have aplasia cutis congenita, a condition characterized by localized areas of missing skin typically occurring on the top of the head (the skull vertex). In some cases, the bone under the skin is also underdeveloped. Individuals with this condition commonly have scarring and an absence of hair growth in the affected area. Abnormalities of the hands and feet are also common in people with Adams-Oliver syndrome. These most often involve the fingers and toes and can include abnormal nails, fingers or toes that are fused together (syndactyly), and abnormally short or missing fingers or toes (brachydactyly or oligodactyly). In some cases, other bones in the hands, feet, or lower limbs are malformed or missing. Some affected infants have a condition called cutis marmorata telangiectatica congenita. This disorder of the blood vessels causes a reddish or purplish net-like pattern on the skin. In addition, people with Adams-Oliver syndrome can develop high blood pressure in the blood vessels between the heart and the lungs (pulmonary hypertension), which can be life-threatening. Other blood vessel problems and heart defects can occur in affected individuals. In some cases, people with Adams-Oliver syndrome have neurological problems, such as developmental delay, learning disabilities, or abnormalities in the structure of the brain.","Curated_USA_Estimate_Source__c":null,"Curated_USA_Estimate__c":null,"Age_at_Onset_Snippet_Text__c":"during Pregnancy and as a Newborn","SourceID__c":"ORPHA:974","Deprecated__c":"No","Disease_Concept_Type__c":"Rare Disease Grouping","MONDO_ID__c":"MONDO:0007034","ORPHANET_ID__c":"ORPHA:974","Replaced_By_ID__c":null,"Display_Spanish_Disease_Name__c":"Síndrome de adams-oliver","Spanish_Description_Source__c":"ORPHA:974","Spanish_Description__c":"Es un trastorno poco frecuente caracterizado por la combinación de anomalías congénitas de las extremidades y alteraciones del cuero cabelludo, a menudo acompañados de trastornos de la osificación del craneal.","Spanish_Disease_Name__c":"síndrome de adams-oliver","Spanish_GARD_Synonym__c":"aplasia cutis congénita con anomalías de las extremidades distales; aplasia cutis congénita con defectos terminales transversales de las extremidades; defectos congénitos del cuero cabelludo con anomalías de reducción distal de las extremidades; defectos congénitos del cuero cabelludo con anomalías distales de las extremidades","Category_Linearization__c":"ORPHA:93890","icd10_id__c":null,"mesh_id__c":null,"omim_id__c":null,"snomed_id__c":null,"umls_id__c":null,"GARD_Disease__c":[{"Curated_Disease_Description__c":"Adams-Oliver syndrome is a rare condition that is present at birth.
