Hypochondroplasia is similar to another skeletal disorder called achondroplasia, but the features tend to be milder. All people with hypochondroplasia have short stature. The adult height for men with this condition ranges from 138 centimeters to 165 centimeters (4 feet, 6 inches to 5 feet, 5 inches). The height range for adult women is 128 centimeters to 151 centimeters (4 feet, 2 inches to 4 feet, 11 inches). People with hypochondroplasia have short arms and legs and broad, short hands and feet. Other characteristic features include a a large head (macrocephaly), limited range of motion at the elbows, a sway of the lower back (lordosis), and bowed legs. These signs are generally less pronounced than those seen in people with achondroplasia and may not be noticeable until early or middle childhood. Affected individuals have a small increased risk of a seizure disorder known as temporal lobe epilepsy. Some studies have reported that a small percentage of people with hypochondroplasia have mild to moderate intellectual disability or learning problems, but other studies have produced conflicting results.","Curated_USA_Estimate_Source__c":null,"Curated_USA_Estimate__c":"50,000","Age_at_Onset_Snippet_Text__c":"at a variety of ages","SourceID__c":"ORPHA:429","Deprecated__c":"No","Disease_Concept_Type__c":"Rare Disease Entity","MONDO_ID__c":"MONDO:0007793","ORPHANET_ID__c":"ORPHA:429","Replaced_By_ID__c":null,"Display_Spanish_Disease_Name__c":"Hipoacondroplasia","Spanish_Description_Source__c":"ORPHA:429","Spanish_Description__c":"Es una displasia ósea primaria con micromelia caracterizada por talla baja desproporcionada, lordosis lumbar leve y extensión limitada de la articulación del codo.","Spanish_Disease_Name__c":"hipoacondroplasia","Spanish_GARD_Synonym__c":null,"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":"Hypochondroplasia is a form of short-limbed dwarfism.
