Summaries for Epiphyseal Dysplasia, Multiple, 2

UniProtKB/Swiss-Prot : 75 Multiple epiphyseal dysplasia 2: A generalized skeletal dysplasia associated with significant morbidity. Joint pain, joint deformity, waddling gait, and short stature are the main clinical signs and symptoms. Radiological examination of the skeleton shows delayed, irregular mineralization of the epiphyseal ossification centers and of the centers of the carpal and tarsal bones. Multiple epiphyseal dysplasia is broadly categorized into the more severe Fairbank and the milder Ribbing types. The Fairbank type is characterized by shortness of stature, short and stubby fingers, small epiphyses in several joints, including the knee, ankle, hand, and hip. The Ribbing type is confined predominantly to the hip joints and is characterized by hands that are normal and stature that is normal or near-normal.

MalaCards based summary : Epiphyseal Dysplasia, Multiple, 2, also known as multiple epiphyseal dysplasia 2, is related to multiple epiphyseal dysplasia and bone deterioration disease. An important gene associated with Epiphyseal Dysplasia, Multiple, 2 is COL9A2 (Collagen Type IX Alpha 2 Chain), and among its related pathways/superpathways are Phospholipase-C Pathway and PI3K-Akt signaling pathway. Affiliated tissues include bone, and related phenotypes are epiphyseal dysplasia and short palm

Disease Ontology : 12 A multiple epiphyseal dysplasia due to collagen 9 anomaly that has material basis in heterozygous mutation in the COL9A2 gene on chromosome 1p34.

NIH Rare Diseases : 53 The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 166002Disease definitionMultiple epiphyseal dysplasia due to collagen 9 anomaly is a rare primary bone dysplasia disorder characterized by normal or mild short stature, early-onset pain and/or stiffness of the joints (mainly affecting knees but also elbows, wrists, ankles and fingers, with relative sparing of the hips) and early degenerative joint disease. Other skeletal anomalies (incl. varus or valgus deformities, osteochondritis dissecans, abnormal carpal shape, free articular bodies) and mild myopathy have also been reported.Visit the Orphanet disease page for more resources.

OMIM : 57 Multiple epiphyseal dysplasia is a clinically and genetically heterogeneous skeletal disorder characterized by joint pain and stiffness, mild short stature, and degenerative joint disease. Onset of the disorder is usually in childhood (summary by Jackson et al., 2010). For a general phenotypic description and a discussion of genetic heterogeneity of EDM, see EDM1 (132400). (600204)
