-
- The May-Hegglin Anomaly consists of abnormalities of the platelets (blood
- elements important in clotting after injuries) and certain leukocytes (white
- blood cells). Symptoms may or may not be present. Treatment is not always
- necessary, and the prognosis is usually good. This anomaly occurs most often
- in Greek or Italian populations.
-
- Symptoms
-
- May-Hegglin Anomaly may be detected at birth although it may remain
- asymptomatic. When symptoms do occur, they include purpura (a purplish or
- brownish red discoloration of the skin due to subcutaneous bleeding),
- nosebleeds, excessive bleeding from the mouth during dental work, headaches,
- and muscular weakness on one side of the body due to intracranial bleeding.
- Withdrawal of steroid therapy used to treat some other disorder may
- precipitate excessive bleeding.
-
- Laboratory investigations reveal giant, oddly shaped platelets and
- characteristic inclusions in the polymorphonuclear leukocytes (a certain kind
- of white blood cells involved with defense against disease). Platelets may
- also be mildly reduced in quantity.
-
- Causes
-
- The May-Hegglin Anomaly is a hereditary condition transmitted by an autosomal
- dominant gene. (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 dominant disorders, a single copy of
- the disease gene (received from either the mother or father) will be
- expressed "dominating" the normal gene and resulting in appearance of the
- disease. The risk of transmitting the disorder from affected parent to
- offspring is 50% for each pregnancy regardless of the sex of the resulting
- child.)
-
- Related Disorders
-
- Other disorders of platelet function include Thrombasthenia, Bernard-Soulier
- Syndrome, Chediak-Higashi Syndrome, the Gray Platelet Syndrome, and various
- defects of collagen induced platelet aggregation. Platelet disorders are
- also associated with congenital conditions such as Wiskott-Aldrich Syndrome,
- Down's Syndrome, Thrombocytopenia with Absent Radius Syndrome, and von
- Willebrand's Disease.
-
- Affected Population
-
- The May-Hegglin anomaly occurs primarily in families of Italian or Greek
- descent.
-
- Therapies: Standard
