      FamilyInfo: Of the 30 families, germline or so- matic origins were found in 9 mothers, 5 maternal grandmothers, and 16 maternal grandfathers. For the 29 incomplete families, origins were found in 14 mothers, 5 maternal grandmothers, and 10 maternal grandfathers. Comparing the two family types shows no significant difference (P=0.29), suggesting that no major bias occurs in the analyses because of the inclusion of incomplete families

      CasePreviousTesting: local labaratory blood tests revealed anemia (hemoglobin concentration 8 g/dl; ref. range 14–18 g/dl), prolongation of prothrombin time (PT) with International Normalized Ratio (INR) within the therapeutic range (between 2.0 and 3.0).
