Cardiac and neurological involvement is common and there is an increased lifetime risk of certain tumors. Costello syndrome belongs to the RASopathies, a group of conditions resulting from germline derived point mutations affecting the RAS-mitogen activated protein kinase pathway.","GARD_Name__c":"Costello syndrome","GARD_Synonym__c":"congenital myopathy with excess of muscle spindles; cstlo; faciocutaneoskeletal syndrome; fcs syndrome","Curated_Disease_Description_Source__c":"GARD:0001550","Curated_Disease_Description__c":"Costello syndrome is a rare disorder that affects many parts of the body. This condition is characterized by delayed development, loose folds of skin (which are especially noticeable on the hands and feet), unusually flexible joints, heart problems, short stature, and distinctive facial features. Children with Costello syndrome are often delayed in reaching developmental milestones, such as speaking, sitting, and walking. Affected individuals may also have intellectual disabilities that can vary in severity. Distinctive facial features in people with Costello syndrome typically include a prominent forehead, full cheeks, and full lips. Infants with Costello syndrome may be larger than average at birth, but most have difficulty eating and grow more slowly than other children. Affected individuals may have gastrointestinal problems that include constipation or a backflow of stomach acids into the esophagus (gastroesophageal reflux or GERD). People with this condition have short stature compared to their family and peers and may have reduced growth hormone levels.  Heart problems are common, including an abnormal heartbeat (arrhythmia), structural heart defects, and a type of heart disease that enlarges and weakens the heart muscle (hypertrophic cardiomyopathy). Neurological problems in people with Costello syndrome include seizures, weak muscle tone (hypotonia), and a structural abnormality of the brain called a Chiari I malformation. Costello syndrome can cause vision problems, such as nearsightedness (myopia), farsightedness (hyperopia), or eyes that do not point in the same direction (strabismus). Hearing loss may also occur. Other signs and symptoms of Costello syndrome can include tight Achilles tendons (which connect the calf muscles to the heel), recurrent respiratory infections, dry and thickened skin, skeletal abnormalities, and dental problems. Beginning in early childhood, people with Costello syndrome have a higher risk of developing certain cancerous and noncancerous tumors compared to the general population. The most common noncancerous tumors associated with this condition are papillomas, which are small, wart-like growths that usually develop around the nose and mouth or near the anus. The most common cancerous tumor associated with Costello syndrome is a childhood cancer called rhabdomyosarcoma, which begins in muscle tissue. Neuroblastoma, a tumor that arises in developing nerve cells, has also  been reported in children and adolescents with this syndrome. In addition, some teenagers with Costello syndrome have developed transitional cell carcinoma, a form of bladder cancer that is usually seen in older adults.  The signs and symptoms of Costello syndrome overlap significantly with those of two other genetic conditions, cardiofaciocutaneous syndrome (CFC syndrome) and Noonan syndrome. In affected infants, it can be difficult to tell the three conditions apart based on their physical features. However, the conditions can be distinguished by their genetic causes and by the specific patterns of signs and symptoms that develop later in childhood.","Curated_USA_Estimate_Source__c":null,"Curated_USA_Estimate__c":"1,000","Age_at_Onset_Snippet_Text__c":"during Pregnancy and as a Newborn","SourceID__c":"ORPHA:3071","Deprecated__c":"No","Disease_Concept_Type__c":"Rare Disease Entity","MONDO_ID__c":"MONDO:0009026","ORPHANET_ID__c":"ORPHA:3071","Replaced_By_ID__c":null,"Display_Spanish_Disease_Name__c":"Síndrome de costello","Spanish_Description_Source__c":"ORPHA:3071","Spanish_Description__c":"Es un síndrome poco frecuente con discapacidad intelectual caracterizado por fallo de medro, talla baja, laxitud articular, piel suave y rasgos faciales distintivos.
