MATN3 pathogenic variants appear to delay the folding of the A- domainwhich elicits an unfolded protein response and results in the retention of mutated matrilin-3 in the rER both in vitro [ Cotterill et alOtten et al ] and in vivo [ Leighton et alNundlall et al ].

Diagnosis can be confirmed by molecular genetic testing of SLC26A2. Sagittal MRI proton-density-weighted fat sat image showing the presence of calcifications and intrasynovial ossification arrow. By definition, the spine is normal; however, Schmorl bodies i. In some families genetic linkage studies have excluded linkage to the five genes in which pathogenic variants are known to be causal; however, additional genetic loci for MED have not yet been determined.

Foot Ankle Surg Dec; 17 4: If a parent is affectedhis or her family members may be at risk. The radiographic manifestations involve the spine and epimetaphyseal regions of the tubular bones. Elsbach described a 4-generation Delft family with what they called bilateral microepiphyseal dysplasia.

A matrilin-3 mutation associated with osteoarthritis does not affect collagen affinity but promotes the formation of wider cartilage collagen fibrils.

Iowa Orthop J ; Novel and recurrent mutations in the C-terminal domain of COMP cluster in two distinct regions and result in a spectrum of phenotypes within the pseudoachondroplasia — multiple epiphyseal dysplasia disease group. ArgTrp [ Kennedy et al aJackson et al ], while two variants p. Histologically, the lesion characteristics are identical to those of osteochondroma 2. In contrast, a recent study of a Korean cohort identified pathogenic variants in 55 individuals as follows: Adult height ranges from to cm.

Generally, the age of onset is between two and multipl years.

Osteochon-droma of the mandibular condyle. Prenatal diagnosis of pregnancies at increased risk is possible if the pathogenic variant has been identified in an affected family member. Mutation in the von Willebrand factor-A domain is not a prerequisite for the MATN3 mutation in multiple epiphyseal dysplasia. MRI findings of dysplasia epiphysealis hemimelica.

Autosomal dominant multiple epiphyseal dysplasia MED should be suspected in individuals with the following clinical and radiographic findings:. MATN3 pathogenic variants result in knee abnormalities that are similar to those in individuals multipel a COL9A2 pathogenic variant ; the hip abnormalities are more severe although not as severe as those in individuals with a COMP pathogenic variant [ Mortier et al ].
