Preferred Label : Factor VIII deficiency;
Type : Other, mainly phenotypes with suspected mendelian basis;
Alternative titles and symbols : Autosomal hemophilia a;
Description : Hensen et al. (1965) described a family in which 8 persons in 4 generations in an
autosomal dominant pattern had factor VIII deficiency, normal bleeding times, and
lack of factor VIII elevation after infusion of hemophilic plasma. Veltkamp et al.
(1968) confirmed these findings and found that no rise of factor VIII occurred in
a boy or a woman with hemophilia A when transfused with plasma from a girl in Hensen's
family. In a restudy of Hensen's family, Veltkamp and Van Tilburg (1974) found that
a member of the family showed de novo synthesis of factor VIII after transfusion with
either normal or hemophilic cryoprecipitate, a finding consistent with von Willebrand
disease. The authors concluded that 'autosomal hemophilia' is merely a variant of
von Willebrand disease. Graham et al. (1975) described a kindred in which hemophilia
A, in every way typical, was observed in grandmother, mother and daughter. Factor
VIII values were 2 to 4%. Unusual lyonization in females heterozygous for the X-linked
disorder was rejected on probabilistic grounds. A previously unrecognized mutation
at the von Willebrand locus was considered. Dominant mutation at a fourth (and previously
unknown) locus involved in factor VIII synthesis and control was considered possible.
Autosomal recessive transmission of hemophilia A is observed with some mutations in
the von Willebrand factor gene (e.g., 193400.0011), which result in defective binding
of factor VIII; this has been referred to as the Normandy type of hemophilia A. *FIELD*
