Presentation
Findings from the literature concerning diagnosis, presenting symptoms, and intervention taken are discussed. Additionally, a patient with a diagnosis of SED congenita who presented with bilateral hand numbness is described. [ncbi.nlm.nih.gov]
The name of the condition indicates that it affects the bones of the spine (spondylo-) and the ends of bones ( epiphyses ), and that it is present from birth ( congenital ). [wikidoc.org]

- Disproportionate Short Stature
Spondyloepiphyseal dysplasia congenita (SEDC) is an autosomal dominantly inherited chondrodysplasia characterized by disproportionate short stature (short trunk), abnormal epiphyses, and flattened vertebral bodies. [ncbi.nlm.nih.gov]
We report a 14-yr-old Korean male who presented with a disproportionately short stature and a short trunk. A pedigree analysis of 3 generations with 6 affected persons revealed an X-linked recessive mode of inheritance. [annlabmed.org]

Features of HCH may include: Short stature with an adult height in the range of 128 -151 cm (4 feet, 2 inches to 4 feet 11 inches); Disproportionate arms and legs with short, broad hands and feet; Macrocephaly (an enlarged head); Limitation of elbow movement [rgauk.org]

Paraneoplastic and autoimmune retinopathies associated with antienolase antibodies are characterized predominantly by cone dysfunction, a slow progression of central vision loss, and eventual optic disc pallor. [entokey.com]

Systemic Features: Dwarfism with kyphosis and a barrel chest are characteristic. The vertebrae are often flattened and malformed and the neck is short. Delayed ossification in the epiphyses and the os pubis is common. [disorders.eyes.arizona.edu]
Physical characteristics include moderate short-stature (dwarfism); moderate to severe spinal deformities; barrel-chest; disproportionately short trunk and neck; disproportionately long arms, and premature osteoarthritis, especially in the hip joints. [diseaseinfosearch.org]

- Coxa Vara
Their height was less than -7SD of average Japanese of the same age, and all were associated with severe coxa vara. [ncbi.nlm.nih.gov]
The 2 types of the disease are the mild coxa vara form, with height maintained (as in our patient) and the severe coxa vara form, with clinical short stature. [consultant360.com]
Other skeletal signs include flattened vertebrae (platyspondyly), a hip joint deformity in which the upper leg bones turn inward (coxa vara), and an inward- and downward-turning foot (called clubfoot). [en.wikipedia.org]

This results in short stature with a very short trunk and limbs, although hands and feet may be more average-sized. People with SED usually have barrel chests, short necks, and abnormal curvature of the spine that may get worse as they age. [connecticutchildrens.org]
