Fibular aplasia-complex brachydactyly syndrome

What it is

A rare syndrome characterised by severe reduction or absence of the fibula and complex brachydactyly. Less than 30 cases have been described in the literature so far. The syndrome is inherited in an autosomal recessive manner and is caused by mutations in the cartilage-derived morphogenetic protein-1 gene (GDF5).

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.
