The growth problems in MOPDII are primordial, meaning they begin before birth, with affected individuals showing slow prenatal growth (intrauterine growth retardation). After birth, affected individuals continue to grow at a very slow rate. The final adult height of people with this condition ranges from 20 inches to 40 inches. Other skeletal abnormalities in MOPDII include abnormal development of the hip joints (hip dysplasia), thinning of the bones in the arms and legs, an abnormal side-to-side curvature of the spine (scoliosis), and shortened wrist bones. In people with MOPDII head growth slows over time; affected individuals have an adult brain size comparable to that of a 3-month-old infant. However, intellectual development is typically normal. People with this condition have a high-pitched, nasal voice and some have a narrowing of the voicebox (subglottic stenosis). Facial features characteristic of MOPDII include a prominent nose, full cheeks, a long midface, and a small jaw. Other signs and symptoms seen in some people with MOPDII include small teeth (microdontia) and farsightedness. Over time, affected individuals may develop areas of abnormally light or dark skin coloring (pigmentation). Many individuals with MOPDII have blood vessel abnormalities. For example, some affected individuals develop a bulge in one of the blood vessels at the center of the brain (intracranial aneurysm). These aneurysms are dangerous because they can burst, causing bleeding within the brain. Some affected individuals have Moyamoya disease, in which arteries at the base of the brain are narrowed, leading to restricted blood flow. These vascular abnormalities are often treatable, though they increase the risk of stroke and reduce the life expectancy of affected individuals.","Curated_USA_Estimate_Source__c":null,"Curated_USA_Estimate__c":null,"Age_at_Onset_Snippet_Text__c":"during Pregnancy, at Birth, and as an Infant","SourceID__c":"ORPHA:2637","Deprecated__c":"No","Disease_Concept_Type__c":"Rare Disease Entity","MONDO_ID__c":"MONDO:0008872","ORPHANET_ID__c":"ORPHA:2637","Replaced_By_ID__c":null,"Display_Spanish_Disease_Name__c":"Talla baja significativa primordial osteodisplásica microcefálica tipo ii","Spanish_Description_Source__c":"ORPHA:2637","Spanish_Description__c":"Es una enfermedad ósea poco frecuente y una forma de enanismo primordial microcefálico caracterizada por un grave retraso del crecimiento pre- y posnatal, con una marcada microcefalia en proporción al tamaño corporal, displasia esquelética, dentición anómala, resistencia a la insulina y un mayor riesgo de enfermedad cerebrovascular.","Spanish_Disease_Name__c":"talla baja significativa primordial osteodisplásica microcefálica tipo ii","Spanish_GARD_Synonym__c":"enanismo primordial osteodisplásico de majewski tipo ii; enanismo primordial osteodisplásico microcefálico tipo ii; mopd tipo ii","Category_Linearization__c":"ORPHA:93419","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":"Microcephalic osteodysplastic primordial dwarfism type II (MOPDII) is a condition characterized by short stature (dwarfism) with other skeletal abnormalities (osteodysplasia) and an unusually small head size (microcephaly).
