Infants usually develop ataxia, psychomotor delay and extraneurological manifestations including failure to thrive, enteropathy, hepatic dysfunction, coagulation abnormalities and cardiac and renal involvement. The phenotype is however highly variable and ranges from infants who die in the first year of life to mildly involved adults.","GARD_Name__c":"PMM2-congenital disorder of glycosylation","GARD_Synonym__c":"carbohydrate deficient glycoprotein syndrome type ia; carbohydrate-deficient glycoprotein syndrome, type ia; cdg - carbohydrate-deficient glycoprotein syndrome type i; cdg 1a; cdg ia; cdg syndrome type ia; cdg-ia; cdg1a; congenital disorder of glycosylation type 1a; congenital disorder of glycosylation type ia; congenital disorder of glycosylation, type ia; jaeken syndrome; phosphomannomutase 2 deficiency; pmm2-cdg; pmm2-cdg (cdg-ia); pmm2-cdg (congenital disorder of glycosylation)","Curated_Disease_Description_Source__c":"GARD:0009826","Curated_Disease_Description__c":"PMM2-congenital disorder of glycosylation (PMM2-CDG, also known as congenital disorder of glycosylation type Ia) is an inherited condition that affects many parts of the body. The type and severity of problems associated with PMM2-CDG vary widely among affected individuals, sometimes even among members of the same family. Individuals with PMM2-CDG typically develop signs and symptoms of the condition during infancy. Affected infants may have weak muscle tone (hypotonia), retracted (inverted) nipples, an abnormal distribution of fat, eyes that do not look in the same direction (strabismus), developmental delay, and a failure to gain weight and grow at the expected rate (failure to thrive). Infants with PMM2-CDG also frequently have an underdeveloped cerebellum, which is the part of the brain that coordinates movement. Distinctive facial features are sometimes present in affected individuals, including a high forehead, a triangular face, large ears, and a thin upper lip. Children with PMM2-CDG may also have elevated liver function test results, seizures, fluid around the heart (pericardial effusion), and blood clotting disorders. About 20 percent of affected infants do not survive the first year of life due to multiple organ failure. The most severe cases of PMM2-CDG are characterized by hydrops fetalis, a condition in which excess fluid builds up in the body before birth. Most babies with hydrops fetalis are stillborn or die soon after birth. People with PMM2-CDG who survive infancy may have moderate intellectual disability, and some are unable to walk independently. Affected individuals may also experience stroke-like episodes that involve an extreme lack of energy (lethargy) and temporary paralysis. Recovery from these episodes usually occurs over a period of a few weeks to several months. During adolescence or adulthood, individuals with PMM2-CDG have reduced sensation and weakness in their arms and legs (peripheral neuropathy), an abnormal curvature of the spine (kyphoscoliosis), impaired muscle coordination (ataxia), and joint deformities (contractures). Some affected individuals have an eye disorder called retinitis pigmentosa that causes vision loss. Females with PMM2-CDG have hypergonadotropic hypogonadism, which affects the production of hormones that direct sexual development. As a result, females with PMM2-CDG do not go through puberty. Affected males experience normal puberty but often have small testes.","Curated_USA_Estimate_Source__c":null,"Curated_USA_Estimate__c":"50,000","Age_at_Onset_Snippet_Text__c":"as a Newborn and as an Infant","SourceID__c":"ORPHA:79318","Deprecated__c":"No","Disease_Concept_Type__c":"Rare Disease Entity","MONDO_ID__c":"MONDO:0008907","ORPHANET_ID__c":"ORPHA:79318","Replaced_By_ID__c":null,"Display_Spanish_Disease_Name__c":"Pmm2-cdg","Spanish_Description_Source__c":"ORPHA:79318","Spanish_Description__c":"Es un trastorno congénito poco frecuente de la N-glicosilación y se caracteriza por disfunción cerebelosa, distribución anómala de la grasa, pezones invertidos, estrabismo e hipotonía.
