A large collection of good genetic markers is needed to map the genes that cause human genetic diseases. Although nearly 400 polymorphic DNA markers for human chromosomes have been described, the majority have only two alleles and are thus uninformative for analysis of genetic linkage in many families. A few known marker systems, however, detect loci that(More)
Ras proteins are conserved from yeasts to mammals and implicated in regulation of the actin cytoskeleton. The flightless-1 (fli-1) gene of Drosophila melanogaster and its homologs in Caenorhabditis elegans and humans encode proteins (FLI-1) comprising a fusion of a leucine-rich repeats (LRRs) domain and a gelsolin-like domain. This LRRs domain is highly(More)
Familial adenomatous polyposis (FAP), a Mendelian disorder that includes familial polyposis coli (FPC) and Gardner syndrome (GS), has an autosomal dominant mode of inheritance. It is characterized by hundreds to thousands of adenomatous polyps that can progress to carcinoma of the colon, suggesting that the gene that harbors the FAP germ-line mutation may(More)
We have constructed a physical map of a 4 cM region on chromosome 17q12–21 that contains the hereditary breast and ovarian cancer gene BRCA1. The map comprises a contig of 137 overlapping yeast artificial chromosomes and P1 clones, onto which we have placed 112 PCR markers. We have localized more than 20 genes on this map, ten of which had not been mapped(More)
Glycerol-3-phosphate acyltransferase 1 (GPAT1) acts as a rate limiting enzyme in triacylglycerol and phospholipid synthesis in mammals. GPAT1 regulates hepatic lipid accumulation associated with metabolic disorders. Here we have identified two transcriptional initiation sites and two promoters (promoter I and II) required for expression of the human GPAT1(More)
SOURCE/DESCRIPTION: A 4.1 kl) TaqI fragment from cosmid EFD145 was subcloned into the AccI site of pUC18. POLYMORPHISM: Rsal identifies a two allele polymorphism (Rl : 2.4 kb, M2 : 1.4 and 1.0 kb) with a constant band at 0.9 kb. TaqI also identifies a two allele polymorphism (Tl : 5.0 kb, T2 : 4.1 kb) without a constant band, but this observation has not(More)
