ORPHA:99642Disease
What it is
Spondyloepimetaphyseal dysplasia, Handigodu type is a rare, genetic, primary bone dysplasia disorder characterized by three distinct phenotypes, namely: 1) patients of average height with painful, osteoarthritic changes of the hip joints and no spinal abnormalities, 2) short-statured patients with predominantly truncal shortening, arm span exceeding height, dysplastic changes of hips and varying degrees of platyspondyly, and 3) patients with dwarfism, various associated skeletal abnormalities (particularly of the knees and hands) and severe epiphyseal dysplasia (of hips, knees, hands, wrists) associated with significant platyspondyly. Most patients cannot walk long distances, and many have decreased joint spaces, as well as sclerotic and cystic changes on imaging.

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.
