ORPHA:93346Disease
What it is
A rare spondyloepimetaphyseal dysplasia characterized by disproportionate short stature from birth, with shortened limbs and other skeletal abnormalities, including lordosis, kyphoscoliosis, flattened vertebrae, coxa vara, and abnormal epiphyses and metaphyses evident within the first year of life. The presence of metaphyseal dysplasia differentiates this condition from spondyloepiphyseal dysplasia congenita (SEDC). Ocular abnormalities, such as myopia, are frequently associated. Characteristic facial features include hypertelorism, a flat facial profile, and the Pierre Robin sequence. An increased risk of cervical (atlantoaxial) instability due to delayed ossification of the odontoid process has also been reported in some patients.

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.
