Carolyn J. Brown
Carolyn J. Brown (born in 1961, Ontario) is a Canadian geneticist and Professor in the Department of Medical Genetics at the University of British Columbia. Brown is known for her studies on X-chromosome inactivation, having discovered the human XIST gene in 1990. Education and early career Brown received her Bachelor of Science in Genetics in 1983 from the University of Guelph, Ontario. She started her PhD thesis work at the University of Toronto in 1983, under the supervision of Hunt Willard, and concluded it at Stanford University, following the moving of Willard’s laboratory in 1989. Brown initiated the studies of the X chromosome in the lab, and her PhD thesis was entitled “Studies of Human X-Chromosome Inactivation”. Her work involved the analysis of genes that “escape” X-chromosome inactivation, being expressed from the (otherwise) inactive X chromosome, as well as the molecular characterization of the X-inactivation center, the genetic locus necessary for si ...

Human Genetics
Human genetics is the study of inheritance as it occurs in human beings. Human genetics encompasses a variety of overlapping fields including: classical genetics, cytogenetics, molecular genetics, biochemical genetics, genomics, population genetics, developmental genetics, clinical genetics, and genetic counseling. Genes are the common factor of the qualities of most human-inherited traits. Study of human genetics can answer questions about human nature, can help understand diseases and the development of effective treatment and help us to understand the genetics of human life. This article describes only basic features of human genetics; for the genetics of disorders please see: medical genetics. Genetic differences and inheritance patterns Inheritance of traits for humans are based upon Gregor Mendel's model of inheritance. Mendel deduced that inheritance depends upon discrete units of inheritance, called factors or genes. Autosomal dominant inheritance Autosomal tr ...

Somatic Cells
A somatic cell (from Ancient Greek σῶμα ''sôma'', meaning "body"), or vegetal cell, is any biological cell forming the body of a multicellular organism other than a gamete, germ cell, gametocyte or undifferentiated stem cell. Such cells compose the body of an organism and divide through the process of binary fission and mitotic division. In contrast, gametes are cells that fuse during sexual reproduction, germ cells are cells that give rise to gametes, and stem cells are cells that can divide through mitosis and differentiate into diverse specialized cell types. For example, in mammals, somatic cells make up all the internal organs, skin, bones, blood and connective tissue, while mammalian germ cells give rise to spermatozoa and ova which fuse during fertilization to produce a cell called a zygote, which divides and differentiates into the cells of an embryo. There are approximately 220 types of somatic cell in the human body. Theoretically, these cells are not germ cells (t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canadian Women Geneticists
Canadians (french: Canadiens) are people identified with the country of Canada. This connection may be residential, legal, historical or cultural. For most Canadians, many (or all) of these connections exist and are collectively the source of their being ''Canadian''. Canada is a multilingual and multicultural society home to people of groups of many different ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. Following the initial period of French and then the much larger British colonization, different waves (or peaks) of immigration and settlement of non-indigenous peoples took place over the course of nearly two centuries and continue today. Elements of Indigenous, French, British, and more recent immigrant customs, languages, and religions have combined to form the culture of Canada, and thus a Canadian identity. Canada has also been strongly influenced by its linguistic, geographic, and ec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

American Society Of Human Genetics
The American Society of Human Genetics (ASHG), founded in 1948, is a professional membership organization for specialists in human genetics. As of 2009, the organization had approximately 8,000 members. The Society's members include researchers, academicians, clinicians, laboratory practice professionals, genetic counselors, nurses, and others who have a special interest in the field of human genetics. As the field of human genetics has expanded, ASHG has founded additional organizations within its membership body, including the following: * National Society of Genetic Counselors, founded in 1979, as an advocacy group for the nascent field of genetic counseling. * American Board of Medical Genetics, founded in 1981, to certify practitioners in human genetics. * American Board of Genetic Counseling, founded in 1991, to certify genetic counselors. * American College of Medical Genetics, founded in 1991, as a specialty board for medical geneticists at the doctoral level.

Natural Sciences And Engineering Research Council
The Natural Sciences and Engineering Research Council of Canada (NSERC; french: Conseil de recherches en sciences naturelles et en génie du Canada, CRSNG) is the major federal agency responsible for funding natural sciences and engineering research in Canada. NSERC directly funds university professors and students as well as Canadian companies to perform research and training. With funding from the Government of Canada, NSERC supports the research of over 41,000 students, trainees and professors at universities and colleges in Canada with an annual budget of CA$1.1 billion in 2015. Its current director is Alejandro Adem. NSERC, combined with the Social Sciences and Humanities Research Council (SSHRC) and the Canadian Institutes of Health Research (CIHR), forms the major source of federal government funding to post-secondary research. These bodies are sometimes collectively referred to as the "Tri-Council" or "Tri-Agency". History NSERC came into existence on 1 May 1978 under th ...

Aneuploidies
Aneuploidy is the presence of an abnormal number of chromosomes in a cell (biology), cell, for example a human cell having 45 or 47 chromosomes instead of the usual 46. It does not include a difference of one or more ploidy#Haploid and monoploid, complete sets of chromosomes. A cell with any number of complete chromosome sets is called a ''ploidy#Euploid, euploid'' cell. An extra or missing chromosome is a common cause of some genetic disorders. Some cancer cells also have abnormal numbers of chromosomes. About 68% of human solid tumors are aneuploid. Aneuploidy originates during cell division when the chromosomes do not separate properly between the two cells (nondisjunction). Most cases of aneuploidy in the autosomes result in miscarriage, and the most common extra autosomal chromosomes among live births are Down syndrome, 21, Edwards syndrome, 18 and Patau syndrome, 13. Chromosome abnormality, Chromosome abnormalities are detected in 1 of 160 live human births. Autosomal aneuplo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
