A white boy and his family were investigated for a haemorrhagic diathesis. Both he and his sister, a primipara between 26 and 28 wk pregnant, in May 1973 had a total lack of factor V, demonstrated an abnormal partial thromboplastin time and a prolonged prothrombin index with normal prothrombin activity. Factor V assays were 10%. Clotting screening tests on the father and another son, who are both heterozygote carriers, were within normal limits, but the specific factor V assays were 48 and 39% respectively, which demonstrates the limitations of routine screening tests as opposed to specific factor V assays. The hereditary patterns in the two documented families in South Africa, and this family, are consistent with a partial dominancy.
