Is TAR syndrome fatal?
Mortality/Morbidity. The major cause of mortality in TAR syndrome is hemorrhage. The incidence of hemorrhage is limited to the first 14 months of life. In a study by Hedberg and associates, 18 of 20 deaths in 76 patients were due to hemorrhagic events; most of patients who died had platelet counts < 10 X 109/L.
Is there a cure for TAR syndrome?
There is no specific treatment for TAR syndrome. Prevention of bleeding and hemorrhage in the first years of life is essential to reduce the clinically significant morbidity. Severe thrombocytopenia may require platelet transfusions.
How do you get TAR syndrome?
TAR syndrome is inherited as an autosomal recessive genetic disorder and caused by two different types of mutations in the RBM8A gene. Recessive genetic disorders occur when an individual inherits two copies of an abnormal gene for the same trait, one from each parent.
