Factor V (Arg 506-->Gln) mutation in young survivors of myocardial infarction.

Many young patients with venous thromboembolic disease are partially resistant to the anticoagulant action of activated protein C as a result of factor V (Arg 506 --> Gln) mutation. The frequency of this mutation in young patients with arterial thrombotic diseases, such as myocardial infarction, is less well established. We studied 100 young patients with myocardial infarction and 100 age- and sex-matched controls. One patient (1%; 95% CL 0.05-6.2) and two controls (2%; 95% CL 0.3-7.7) were heterozygotes for the mutation; there was no homozygote in either group. Hence, premature myocardial infarction is not associated with heterozygosity for factor V (Arg 506 --> Gln) mutation.

Apparently dominant transmission of a recessive disease: deficiency of factor VII in Iranian Jews.

In inherited disorders transmitted as autosomal recessive traits the children of affected individuals are usually asymptomatic and phenotypically normal because they are heterozygous for the defect. In an Iranian Jewish family with moderately severe deficiency of coagulation factor VII (an autosomal recessive bleeding disorder) the son of an affected woman was also affected. DNA analysis of the factor VII gene showed that this unusual situation was due to the fact that he inherited an abnormal allele with the Ala244Val missense mutation from both the homozygous mother and the heterozygous father. The parents, although not overtly consanguineous, belong to the same ethnic group of Iranian Jews, among whom this factor VII gene mutation reaches high frequencies (between 2 and 3%) in the heterozygous state.
