Symbrachydactyly of hands and feet

What it is

Symbrachydactyly of hands and feet is a rare, non-syndromic limb reduction defect disorder characterized by unilateral or bilateral brachydactyly, cutaneous syndactyly and global hypoplasia of the hand and/or foot, with underlying muscles, tendons, ligaments and bones being affected but without other associated limb anomalies. Patients typically present short, stiff, webbed or missing fingers and/or toes which are often replaced with small stumps (nubbins) with residual nails.

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.
