Familial osteodysplasia, Anderson type

What it is

Familial osteodysplasia, Anderson type is a rare, genetic dysostosis disorder characterized by craniofacial bone abnormalities (i.e. midface hypoplasia, broad, flat nasal bridge, narrow, thin prognathic mandible with pointed chin, malocclusion, partial dental agenesis) associated with additional osseous anomalies, including scoliosis, calvarial thinning, pointed spinous processes, clinodactyly and abnormal phalanges. Elevated erythrocyte sedimentation rate, hyperuricemia and hypertension have also been reported. There have been no further descriptions in the literature since 1982.

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.

Related health topics

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