-
-
- Dubowitz Syndrome is a possible autosomal recessive hereditary disease
- characterized by short stature and a peculiar facial structure. Onset of
- this very rare developmental disorder is before or immediately after birth.
-
- Symptoms
-
- Children with Dubowitz Syndrome show a low birth weight; usually about 5 lb.
- at full term. Other symptoms may include:
-
- 1. Short stature,
- 2. Facial irregularities such as a relatively high nasal bridge,
- 3. Low ridges over the eyes (hypoplasia of supraorbital ridges),
- 4. Abnormalities of the jaw area (zygoma, malar eminence, mandible),
- 5. Eyes set wide apart (ocular hypertelorism),
- 6. Narrow drooping eyelids (ptosis and blepharophimosis),
- 7. Prominent ears,
- 8. Occasionally a cleft palate,
- 9. High-pitched voice,
- 10. Delay in eruption of the teeth,
- 11. Dental decay,
- 12. Thickening of the skin,
- 13. Eczema of face, ears, knees and elbows,
- 14. Sparseness of hair.
-
- Some children with Dubowitz Syndrome may be mildly mentally retarded, but
- most have normal intelligence with some memory deficits and/or learning
- disabilities, and they are hyperactive. Their speech usually sounds
- abnormal.
-
- Causes
-
- Dubowitz Syndrome is possibly an autosomal recessive hereditary disorder.
- (Human traits including the classic genetic diseases, are the product of the
- interaction of two genes for that condition, one received from the father and
- one from the mother. In recessive disorders, the condition does not appear
- unless a person inherits the same defective gene from each parent. If one
- receives one normal gene and one gene for the disease, the person will be a
- carrier for the disease, but usually will show no symptoms. The risk of
- transmitting the disease to the children of a couple, both of whom are
- carriers for a recessive disorder, is twenty-five percent. Fifty percent of
- their children will be carriers, but healthy as described above. Twenty-five
- percent of their children will receive both normal genes, one from each
- parent and will be genetically normal.)
-
- The genetic defect causes intrauterine (before birth) or postnatal (after
- birth) growth retardation. In some cases, a recessive mode of inheritance
- cannot be identified and it is presumed to be a spontaneous mutation.
-
- Affected Population
-
- Both sexes are equally affected by Dubowitz Syndrome. It is a very rare
- developmental disorder.
-
- Related Disorders
-
- Bloom syndrome is a hereditary form of dwarfism accompanied by abnormalities
- of the facial skin. Unusual sensitivity to sunlight and poor resistance to
- infections are symptoms of this disorder. Later in life, cancers may
- develop. Males of Eastern European Jewish descent are predominantly
- affected.
-
- Therapies: Standard
-
- Treatment of Dubowitz Syndrome is symptomatic and supportive.
-
- Therapies: Investigational
