Dominant genes for colorectal cancer are not rare

Annals of Human Genetics, 1992
SummaryThe genetic basis for colorectal cancer was investigated by complex segregation analysis of a published series of consecutive pedigrees ascertained through patients undergoing treatment for colorectal cancer. Analysis favoured a dominant gene or genes with a frequency of 0·006 with a lifetime penetrance of 0·63.

Severe Renal Dysgenesis Produced by a Dominant Gene

Archives of Pediatrics & Adolescent Medicine, 1976
A woman with the autosomal dominant syndrome of preauricular pits, cervical fistulae, and partial deafness gave birth to two children with preauricular pits and severe renal dysgenesis. The facies had some features of the Potter facies of renal agenesis. One child died soon after birth because of pneumothorax and immature development of the lungs.

Connexin 26 gene linked to a dominant deafness

Nature, 1998
A high proportion of all cases of congenital deafness is causedby mutations in a gene coding for a gap-junction protein,connexin 26. The deafness associated with this gene, Cx26, is the autosomal recessive form, DFNB1(refs 1–3); its involvement in autosomal dominant forms of deafness has remained controversial4.

Genetic mechanisms for dominant VH gene expression. The VHB512 gene

The Journal of Immunology, 1992
Abstract A total of 37 mAb with reactivity for dextran B512 have been studied; 30 of them were products of independent rearrangements and 21 made use of the same VH gene, the VHB512 gene. These results unambiguously established that the immune response to dextran in the high responder mouse strain C57BL/6 was restricted.

Melanin inhibitor: a dominant gene in the domestic cat

Journal of Heredity, 1980
Melanin inhibitor (symbol I) is shown to be inherited as a dominant to the wild type and independent of the albino locus. The gene inhibits the formation of melanin in the less intensely pigmented regions of the coat, namely, the agouti areas between the tabby pattern and the proximal portion of the hair.

Testing for the presence of a partially penetrant dominant gene

Mutation Research Letters, 1983
Favor, in the Appendix to a paper by Ehling and his collaborators (Ehling et al., 1982), develops a method that tests for the presence of a partially penetrant dominant cataract mutation in a suspected parent (showing lens opacity) outcrossed to a homozygous strain-101 mouse when no individual with lens opacity is observed in the progeny.

TransgenicArabidopsis tester lines with dominant marker genes

Molecular and General Genetics MGG, 1996
The map positions of a set of eight T-DNA insertions in the Arabidopsis genome have been determined by using closely linked visible markers. The insertions are dispersed over four of the five chromosomes. Each T-DNA insert contains one or more of the chimeric marker genes neomycin phosphotransferase (neo), hygromycin phosphotransferase (hpt ...

Polyoma tumorigenesis in mice: Evidence for dominant resistance and dominant susceptibility genes of the host

Virology, 1992
We have determined the tumor responses of nine inbred mouse strains and of two F1 hybrids following inoculation with polyoma virus. The results showed wide variations in the frequencies of mice developing tumors. Correlation with H-2 haplotype were evident.

A Dominant Gene for Male Sterility in Wheat

Plant Breeding, 1986
AbstractA dominant gene inducing male sterility in wheat is described. It is located on the short arm of chromosme 4D with a recombination percentage of 31.16 with the centromere. The potential use of this allele in breeding and cytogenetic studies in both tetraploid and hexaploid with is discussed.

On survival probabilities of mutant genes and the evolution of dominance

Theoretical Population Biology, 1976
Abstract Intrinsic biological resemblance between two types is measured in terms of a correlation between their fitnesses under various possible environmental conditions. A tendency toward dominance is defined as the intrinsic biological resemblance between homozygote and heterozygote.
