Craniofacial dysostosis-diaphyseal hyperplasia syndrome

What it is

A rare primary bone dysplasia with increased bone density characterized by craniofacial dysostosis with a small cranium and thin skull bone, depressions over the frontoparietal and occipitoparietal sutures, marked hypoplasia of mandible, exophthalmos, cortical sclerosis of the long bones and normal intelligence. The long bones are short and bent, and thickening of bone cortex occurs during the pubertal and post-pubertal periods and increases with age. There have been no further descriptions in the literature since 1995.

Classified as

Malformation syndrome

Prevalence figures describe populations, not individuals, and are often estimates from a single study. Where the figure is an incidence or a birth prevalence, it says so.

Signs and symptoms

These ranges are how often a sign appears across everyone diagnosed, not a prediction for one person — most people have some of these and not others. Orphanet also records findings that are specifically absent in this disease; those are in the data but not listed here.

ICD-10 codes

ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.

Reached through the ICD-10 categories this disease is filed under, so these describe the broader group rather than this disease specifically.
