The kininogen (KGN) gene status was examined in 4 families with both high molecular weight (HMW) and low molecular weight (LMW) KGM deficiency and one family with only HMW-KGN deficiency reported in Japan. No abnormal HMW-KGN or LMW-KGN was detected in those with these deficiencies by immunoblot analysis using monoclonal antibodies (HKG-H12, HKG-L7, HKG-L17) for human HMW-KGN. HMW-DNA prepared from peripheral blood leucocytes was digested with endonuclease, EcoRI, Bam HI, Hind III, Sca I, Bg1II, Xba I, Msp I, Pst I, Hpa I, PvuII, HaeIII, Rsa I, Alu I, or Taq I, and studied by Southern blot analysis with human LMW prekininogen cDNA (phKG 36) as a probe. A gross deletion or insertion of the KGN gene was not detected in those with both HMW- and LMW-KGN deficiencies. On the other hand, partial defect in intron 7 (G) was found in those with only HMW-KGN deficiency, suggesting that this defect might be related to abnormality of the alternative RNA splicing events for HMW-prekininogen mRNA.

Five broad host range lipid-containing bacteriophages PRD1, PR3, PR4, PR5 and L17 isolated from different parts of the world were compared using biological and structural criteria. Virus morphology as well as genome sizes appeared to be identical. However, these viruses could be distinguished by restriction endonuclease mapping and by their structural protein patterns in SDS--gel electrophoresis. The viruses studied thus form a very close group of lipid-containing bacteriophages. We suggest PRD1 as a model organism for this group and that the group be called the PRD1 phage group.

The t(3;6)(p14;p11) chromosome translocation was identified in a family in which three members developed hematologic malignancies. To help characterize the region on chromosome 3 surrounding this translocation breakpoint, two flanking lambda clones, MS156 and MJ1525, were linked by pulsed-field gel electrophoresis to the same 510-kb NotI fragment on chromosome 3. MS156 was localized to a region proximal to the breakpoint of a der(3) chromosome somatic cell hybrid (derived from the t(3;6) cell line), and MJ1525 localized distal to the breakpoint. MJ1525 was used to screen the CEPH yeast artificial chromosome (YAC) library, which revealed a YAC, 195F3, that spanned the breakpoint. Subcloning into Lambda DASH II and production of a contiguous array of overlapping lambda clones revealed a clone, L17, that spanned the breakpoint. A rare restriction endonuclease map for the YAC 195F3 was constructed, and multiple clusters of rare restriction sites within the YAC were identified, possibly indicating the disruption of a gene by the t(3;6) translocation breakpoint.
