People with cartilage-hair hypoplasia have unusually short limbs and short stature from birth. They typically have malformations in the cartilage near the ends of the long bones in the arms and legs (metaphyseal chondrodysplasia), which then affects development of the bone itself. Most people with cartilage-hair hypoplasia are unusually flexible in some joints, but they may have difficulty extending their elbows fully. Affected individuals have hair that is lighter in color than that of other family members because the core of each hair, which contains some of the pigment that contributes the hair's color, is missing. The missing core also makes each strand of hair thinner, causing the hair to have a sparse appearance overall. Unusually light-colored skin (hypopigmentation), malformed nails, and dental abnormalities may also be seen in this disorder. The extent of the immune deficiency in cartilage-hair hypoplasia varies from mild to severe. Affected individuals with the most severe immune problems are considered to have severe combined immunodeficiency (SCID). People with SCID lack virtually all immune protection from bacteria, viruses, and fungi and are prone to repeated and persistent infections that can be very serious or life-threatening. These infections are often caused by 'opportunistic' organisms that ordinarily do not cause illness in people with a normal immune system. Most people with cartilage-hair hypoplasia, even those who have milder immune deficiency, experience infections of the respiratory system, ears, and sinuses. In particular, the chicken pox virus (varicella) often causes dangerous infections in people with this disorder. Autoimmune disorders, which occur when the immune system malfunctions and attacks the body's tissues and organs, occur in some people with cartilage-hair hypoplasia. Affected individuals are also at an increased risk of developing cancer, particularly certain skin cancers (basal cell carcinomas), cancer of blood-forming cells (leukemia), and cancer of immune system cells (lymphoma). Some people with cartilage-hair hypoplasia experience gastrointestinal problems. These problems may include an inability to properly absorb nutrients or intolerance of a protein called gluten found in wheat and other grains (celiac disease). Affected individuals may have Hirschsprung disease, an intestinal disorder that causes severe constipation, intestinal blockage, and enlargement of the colon. Narrowing of the anus (anal stenosis) or blockage of the esophagus (esophageal atresia) may also occur.","Curated_USA_Estimate_Source__c":null,"Curated_USA_Estimate__c":"50,000","Age_at_Onset_Snippet_Text__c":"during Pregnancy, at Birth, and as an Infant","SourceID__c":"ORPHA:175","Deprecated__c":"No","Disease_Concept_Type__c":"Rare Disease Grouping","MONDO_ID__c":"MONDO:0009595","ORPHANET_ID__c":"ORPHA:175","Replaced_By_ID__c":null,"Display_Spanish_Disease_Name__c":"Hipoplasia de cartílago-cabello","Spanish_Description_Source__c":"ORPHA:175","Spanish_Description__c":"La hipoplasia de cartílago-cabello es una enfermedad que afecta a la metáfisis de los huesos causando baja estatura desde el nacimiento.","Spanish_Disease_Name__c":"hipoplasia de cartílago-cabello","Spanish_GARD_Synonym__c":"condrodisplasia metafisaria autosómica recesiva; hipoplasia de cartílago-pelo","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":"Cartilage-hair hypoplasia is a disorder of bone growth characterized by short stature (dwarfism) with other skeletal abnormalities; fine, sparse hair (hypotrichosis); and abnormal immune system function (immune deficiency) that can lead to recurrent infections.

Undertubulation refers to a broad, widened form of the shafts (diaphyses) of long bones.","HPO_Feature_URL__c":"https://hpo.jax.org/browse/term/HP:0005019","HPO_Synonym__c":"Diaphyseal widening; Thickening of shaft or central part of long bones; Undertubulated long bones; Undertubulation of diaphyses","HPO_Name__c":"Diaphyseal undertubulation","Feature_System__c":"Musculoskeletal System","HPO_Feature_Type__c":"Symptom"}},{"Provided_By__c":"ORPHA:175","HPO_Frequency__c":"Very frequent (80-99%)","Feature__r":{"HPO_Description__c":"Decreased density/number of eyebrow hairs.","HPO_Feature_URL__c":"https://hpo.jax.org/browse/term/HP:0045075","HPO_Synonym__c":"Hypotrichosis of eyebrow; Sparse eyebrow; Sparse eyebrows","HPO_Name__c":"Sparse eyebrow","Feature_System__c":"Skin System","HPO_Feature_Type__c":"Symptom"}}],"tags":{"Cause":["Genetics"],"Disease Category":["Genetics","Dermatology","Congenital Abnormality"],"Specialist":["Genetics","Ophthalmology","Immunology","Dermatology","Orthopedics","Neuro-Ophthalmology","Pediatrics"],"Account":["Dermatology","Primary Immune Deficiencies","Ectodermal dysplasia"]},"synonyms":["autosomal recessive metaphyseal chondrodysplasia"," cartilage hair hypoplasia"," cartilage hair syndrome"," cartilage-hair hypoplasia"," cartilage-hair hypoplasia syndrome"," chh"," mckusick type metaphyseal chondrodysplasia"]}
