Molecular mapping within the mouse albino-deletion complex.
Induced germ-line deletion mutations in the mouse provide a malleable experimental system for in-depth molecular and functional analysis of large segments of the mammalian genome. To obtain an initial bank of molecular probes for the region of mouse chromosome 7 associated with the albino-deletion complex, random anonymous DNA clones, derived from a library constructed from flow-sorted chromoso...
متن کاملThe albino-deletion complex of the mouse: molecular mapping of deletion breakpoints that define regions necessary for development of the embryonic and extraembryonic ectoderm.
Previous complementation analyses with five (c11DSD, c5FR60Hg, c2YPSj, c4FR60Hd, c6H) of the mouse albino deletions defined at least two genes on chromosome 7, known as eed and exed, which are necessary for development of the embryonic and extraembryonic ectoderm, respectively, of early postimplantation embryos. The region of chromosome 7 containing these two genes has now been accessed at the ...
متن کاملMolecular and functional mapping of the piebald deletion complex on mouse chromosome 14.
The piebald deletion complex is a set of overlapping chromosomal deficiencies surrounding the endothelin receptor B locus collected during the Oak Ridge specific-locus-test mutagenesis screen. These chromosomal deletions represent an important resource for genetic studies to dissect the functional content of a genomic region, and several developmental defects have been associated with mice homo...
متن کاملThe albino deletion complex and early postimplantation survival in the mouse.
The albino deletion complex in the mouse represents 37 overlapping chromosomal deficiencies that have been arranged into at least twelve complementation groups. Many of the deletions cover regions of chromosome 7 that contain genes necessary for early embryonic development. The work reported here concentrates on two of these deletions (c6H, c11DSD), both of which were known to be lethal around ...
متن کاملThe albino-deletion complex in the mouse defines genes necessary for development of embryonic and extraembryonic ectoderm.
A detailed embryological analysis has been undertaken on embryos carrying the c4FR60Hd-, c5FR60Hg- or c2YPSj-albino deletions of mouse chromosome 7. Embryos homozygous for the c4FR60Hd deletion are abnormal at day 7.5 of gestation. The extraembryonic ectoderm does not develop, and primitive-streak formation and mesoderm production do not occur. In contrast, extensive development of the extraemb...
