A newly recognized autosomal recessive syndrome with abnormal vertebral ossification, rib abnormalities, and nephrogenic rests.
We describe three cases of a severe malformation syndrome in siblings of both sexes. The characteristic features observed were absent intrauterine ossification of an apparently normal cartilaginous spinal column; rib abnormalities, with unossified segments and posterior gaps; thoracic hypoplasia; and multiple intralobar nephrogenic rests in the kidneys. This syndrome can be identified in early pregnancy by ultrasound scans due to the lack of ossification of the thoraco-lumbar spine and its association with increased nuchal translucency thickness. We suggest that this is a newly recognized autosomal recessive syndrome.
