Ordering of human chromosome 3p markers by radiation hybrid mapping.
To construct a panel of radiation hybrids (RHs) for human chromosome 3p mapping, mouse microcell hybrid cells, A9(neo3/t)-5, containing a single copy of human chromosome 3p with pSV2neo plasmid DNA integrated at 3p21-p22 were irradiated and fused to mouse A9 cells. A panel of 96 RHs that retain several sizes and portions of human chromosome 3p segments was used to map 25 DNA markers for chromosome 3p. Eight of them, H28, H29, H32, H33, H35, H38, H48, and H64, were cloned from Alu-primed PCR products using A9(neo3/t)-5 cell DNA as a template. The most likely order of the 24 markers, except for H28, based on the statistical ordering method proposed by Falk, was cen-D3S4-D3S3-D3S30-H29-D3S13-D3S2-+ ++H48-D3F15S2-D3S32-D3S23-CCK-H35-H33- D3S11-D3S12-RARB-THRB(ERBA2-pBH302)- H64-H38-RAF1-D3S18-H32-D3S22-pter. The order and location of these markers were in good agreement with those previously determined by other mapping methods, suggesting that a panel of these 96 RHs is a valuable source for a rapid mapping of human chromosome 3p markers.
