Blomstrand chondrodysplasia is a rare lethal skeletal dysplasia with presumed autosomal-recessive inheritance. A family with 2 affected fetuses was studied. One fetus demonstrated a severe skeletal dysplasia at routine transabdominal ultrasound examination at 18.5 weeks of gestation. The pregnancy w

โฆ Synopsis
We present the clinical, roentgenographic, and histologic abnormalities in a stillborn infant with Blomstrand osteochondrodysplasia. Parental consanguinity and multiplex occurrence in the patients' sibship confirm the hypothesis of autosomal recessive inheritance of this monogenic lethal entity. The unknown genetic defect interferes severely with skeletal growth through lack of chondrocyte multiplication and apparent uncoupling of the processes of enchondral ossification and skeletal growth.

We report on a previously undescribed form of lethal osteosclerotic skeletal dysplasia in sibs from nonconsanguineous parents. Radiographic findings included increased density in the base of the skull, clavicles, vertebrae, ribs, and the metaphyseal regions of the long bones. There was midface hypop
