Disease characteristics

Excerpted from the GeneReview: Schimke Immunoosseous Dysplasia
Schimke immunoosseous dysplasia (SIOD) is characterized by spondyloepiphyseal dysplasia (SED) resulting in short stature, nephropathy, and T cell deficiency. Radiographic manifestations of SED include ovoid and mildly flattened vertebral bodies, small ilia with shallow dysplastic acetabular fossae, and small deformed capital femoral epiphyses. Nearly all affected individuals have progressive steroid-resistant nephropathy, usually developing within five years of the diagnosis of growth failure and terminating with end-stage renal disease. The majority of tested individuals have T cell deficiency and an associated risk for opportunistic infection, a common cause of death. SIOD involves a spectrum that ranges from an infantile or severe early-onset form with a greater risk of death during childhood to a juvenile or milder later-onset form with likely survival into adulthood if renal disease is appropriately treated. [from GeneReviews]

Additional descriptions

From OMIM
Schimke immunoosseous dysplasia (SIOD) is an autosomal recessive disorder characterized by spondyloepiphyseal dysplasia, renal dysfunction and T-cell immunodeficiency. Additionally, approximately half of affected individuals have hypothyroidism, half have episodic cerebral ischemia, and one-tenth have bone-marrow failure. SIOD has a marked variation in severity, ranging from in utero onset of growth retardation and death within the first 5 years of life to a milder course with the onset of symptoms late in the first decade or early in the second decade of life (summary by Boerkoel et al., 2002).  http://www.omim.org/entry/242900
From MedlinePlus Genetics
Schimke immuno-osseous dysplasia is a condition characterized by short stature, kidney disease, and a weakened immune system. People with this condition have flattened spinal bones (vertebrae) that shorten their neck and trunk. The adult height for people with this condition is typically between 3 and 5 feet. Additional skeletal problems in people with Schimke immuno-osseous dysplasia include abnormalities of the hip joints and the end of the leg bones where they meet the hip joint. These skeletal problems can cause the hip joints to break down (degenerate) over time, leading to joint pain and a limited range of movement. This combination of skeletal problems and spinal abnormalities is called spondyloepiphyseal dysplasia as it affects the bones of the spine (spondylo-) and the ends of long bones (epiphyses) in the legs. It affects most people with Schimke immuno-osseous dysplasia.People with Schimke immuno-osseous dysplasia often have kidney (renal) disease that may lead to life-threatening renal failure and end-stage renal disease (ESRD). 

Individuals with Schimke immuno-osseous dysplasia also have a shortage of immune system cells called T cells. T cells identify foreign substances and defend the body against infection. This shortage of T cells causes people with Schimke immuno-osseous dysplasia to have recurrent infections.

Other features frequently seen in people with Schimke immuno-osseous dysplasia include an exaggerated curvature of the lower back (lordosis); darkened patches of skin (hyperpigmentation), typically on the chest and back; abnormalities of the teeth; and a broad nasal bridge with a rounded tip of the nose.

Less common signs and symptoms of Schimke immuno-osseous dysplasia include an accumulation of fatty deposits in the lining of the arteries (atherosclerosis), reduced blood flow to the brain (ischemic stroke), migraine-like headaches, an underactive thyroid gland (hypothyroidism), a decrease in the number of blood cells (anemia), a lack of sperm (azoospermia), and irregular menstruation.

In severe cases, individuals with Schimke immuno-osseous dysplasia do not survive past childhood. In mild cases, people with Schimke immuno-osseous dysplasia can survive into adulthood.  https://medlineplus.gov/genetics/condition/schimke-immuno-osseous-dysplasia

Waddling gait
MedGen UID:
66667
Concept ID:
C0231712
Finding
Weakness of the hip girdle and upper thigh muscles, for instance in myopathies, leads to an instability of the pelvis on standing and walking. If the muscles extending the hip joint are affected, the posture in that joint becomes flexed and lumbar lordosis increases. The patients usually have difficulties standing up from a sitting position. Due to weakness in the gluteus medius muscle, the hip on the side of the swinging leg drops with each step (referred to as Trendelenburg sign). The gait appears waddling. The patients frequently attempt to counteract the dropping of the hip on the swinging side by bending the trunk towards the side which is in the stance phase (in the German language literature this is referred to as Duchenne sign). Similar gait patterns can be caused by orthopedic conditions when the origin and the insertion site of the gluteus medius muscle are closer to each other than normal, for instance due to a posttraumatic elevation of the trochanter or pseudarthrosis of the femoral neck.

Astigmatism
MedGen UID:
2473
Concept ID:
C0004106
Disease or Syndrome
Astigmatism (from the Greek 'a' meaning absence and 'stigma' meaning point) is a condition in which the parallel rays of light entering the eye through the refractive media are not focused on a single point. Both corneal and noncorneal factors contribute to refractive astigmatism. Corneal astigmatism is mainly the result of an aspheric anterior surface of the cornea, which can be measured readily by means of a keratometer; in a small fraction of cases (approximately 1 in 10) the effect is neutralized by the back surface. The curvature of the back surface of the cornea is not considered in most studies, because it is more difficult to measure; moreover, in the case of severe corneal astigmatism, there is evidence that both surfaces have the same configuration. Noncorneal factors are errors in the curvature of the 2 surfaces of the crystalline lens, irregularity in the refractive index of the lens, and an eccentric lens position. Since the cornea is the dominant component of the eye's refracting system, a highly astigmatic cornea is likely to result in a similarly astigmatic ocular refraction (summary by Clementi et al., 1998).
Myopia
MedGen UID:
44558
Concept ID:
C0027092
Disease or Syndrome
Nearsightedness, also known as myopia, is an eye condition that causes blurry distance vision. People who are nearsighted have more trouble seeing things that are far away (such as when driving) than things that are close up (such as when reading or using a computer). If it is not treated with corrective lenses or surgery, nearsightedness can lead to squinting, eyestrain, headaches, and significant visual impairment.\n\nNearsightedness usually begins in childhood or adolescence. It tends to worsen with age until adulthood, when it may stop getting worse (stabilize). In some people, nearsightedness improves in later adulthood.\n\nFor normal vision, light passes through the clear cornea at the front of the eye and is focused by the lens onto the surface of the retina, which is the lining of the back of the eye that contains light-sensing cells. People who are nearsighted typically have eyeballs that are too long from front to back. As a result, light entering the eye is focused too far forward, in front of the retina instead of on its surface. It is this change that causes distant objects to appear blurry. The longer the eyeball is, the farther forward light rays will be focused and the more severely nearsighted a person will be.\n\nNearsightedness is measured by how powerful a lens must be to correct it. The standard unit of lens power is called a diopter. Negative (minus) powered lenses are used to correct nearsightedness. The more severe a person's nearsightedness, the larger the number of diopters required for correction. In an individual with nearsightedness, one eye may be more nearsighted than the other.\n\nEye doctors often refer to nearsightedness less than -5 or -6 diopters as "common myopia." Nearsightedness of -6 diopters or more is commonly called "high myopia." This distinction is important because high myopia increases a person's risk of developing other eye problems that can lead to permanent vision loss or blindness. These problems include tearing and detachment of the retina, clouding of the lens (cataract), and an eye disease called glaucoma that is usually related to increased pressure within the eye. The risk of these other eye problems increases with the severity of the nearsightedness. The term "pathological myopia" is used to describe cases in which high myopia leads to tissue damage within the eye.
