Cerebral infarct associated with factor V Leiden mutation in a boy with hemophilia A.

An 11-year-old boy with mild hemophilia A was admitted to our hospital because of focal convulsions. Magnetic resonance imaging showed an old occipital infarct. Protein C, S, antithrombin III, anticardiolipin antibodies and fibrinogen were normal. Heterozygosity for factor V Leiden mutation was detected. We suggest that factor V Leiden mutation should be studied in hemophiliacs with thrombosis.

Prenatal diagnosis of hemoglobinopathies in Turkey: Hacettepe experience.

Prenatal diagnosis of hemoglobinopathies was performed in 250 fetuses at risk for hemoglobinopathies. The main diagnostic procedures were in vitro hemoglobin synthesis analysis in fetal blood and analysis of DNA obtained from chorionic villus samples. Sixty-six percent of the fetuses were at risk for beta thalassemia major and 28% for sickle cell anemia. Beta thalassemia mutations were heterogenous, and 51 fetuses examined by the DNA technique were found to be at risk for at least 20 different combinations.

Compound heterozygosity for hemoglobin Knossos [alpha 2 beta 2 27 (B9) Ala-Ser] and IVS I-1 mutation.

A three-year-old female with compound heterozygosity for Hb Knossos and IVS-I-1 mutation is presented. On physical examination she had no abnormality except for pallor. Hb was 6.9 g/dl, MCV 61 fl, Hb A2 2% and Hb F 38.5%. Acrylamidegel electrophoresis at a pH of 6 revealed the presence of Hb Knossos in the child and her father. DNA studies revealed that the child was compound heterozygous for Hb Knossos and the IVS I-1 mutation. When the clinical expression of this combination in a previously reported patient with Hb Knossos/FSC8 mutation is compared, it is shown that the newly presented patient has a more severe condition, indicating that the mutations in the trans of Hb Knossos may play a role in the phenotypical expression of the disease.
