| Parastremmatic dwarfism is a very rare chondrodysplasia with characteristics of severe dwarfism, kyphoscoliosis, stiffness of large joints and distortion of lower limbs. Radiographs show bowing of long bones, platyspondyly and a very rough, irregular metaphyseal and epiphyseal bone texture. The syndrome is caused by a heterozygous mutation in the TRPV4 gene (12q24.1). |
