A genetic disorder is a health problem caused by one or more abnormalities in the genome.It can be caused by a mutation in a single gene (monogenic) or multiple genes (polygenic) or by a chromosome abnormality.
The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child. There are over 6,000 known genetic disorders in humans.
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.
The missing heritability problem was named as such in 2008 (after the "missing baryon problem" in physics).The Human Genome Project led to optimistic forecasts that the large genetic contributions to many traits and diseases (which were identified by quantitative genetics and behavioral genetics in particular) would soon be mapped and pinned down to specific genes and their genetic variants by ...
Phenocopies is when environmental and/or behavioral modifiers causes an illness which mimics the phenotype of a genetic inherited disease. Because of phenocopies, determining the degree of penetrance for a genetic disease requires full knowledge of the individuals attending the studies, and the factors that may or may not have caused their illness.
The candidate gene approach to conducting genetic association studies focuses on associations between genetic variation within pre-specified genes of interest, and phenotypes or disease states. This is in contrast to genome-wide association studies (GWAS), which is a hypothesis-free approach that scans the entire genome for associations between ...
In September, 2011, an iPhone App of the English Talking Glossary was released by NHGRI and made available as a free download in the Apple App store. The App version contains all 3-D animations, high quality illustrations, the "Test Your Gene IQ" quiz, and similar user functions such as "Suggest a Term" and "Mail This Term to a Friend."
The risk of multifactorial diseases may get increased due to environmental influences. The disease is not sex-limited but it occurs more frequently in one gender than the other; females are more likely to have neural tube defects compared to males. The disease occurs more commonly in a distinct ethnic group (i.e., Africans, Asians, Caucasians etc.)
