General

Disease Name
Chondrodysplasia, Disproportionate Short-limbed
Mutation
c.2083C>T
Test Type
Genetic Disease/Disorder
Details

Details 2
As reported by Bingel and Sande (1982): "Radiographic changes included flaring and increased width of the distal metaphyses of the radius and ulna, delayed ossification of the cuboid bones of the carpus, and reduction in length of the vertebral bodies. The zone of chondrocyte proliferation was decreased in width and contained areas of abnormal cell column formation alternated with wide areas of matrix. Chondrocytes in all zones contained one or more inclusions bounded by a smooth discontinuous membrane. The material within the inclusions appeared homogeneous and stained blue-green with Movat's pentachrome and deep blue with alcian blue-periodic acid-Schiff at pH 1.0 and 2.6. The distribution of ruthenium red granules in the matrix frequently revealed poor differentiation into territorial and interterritorial zones". (from OMIA)
