Genetics

Description of all the epigenetic modifications across the whole genome. Unlike the genome (DNA sequence), different cells within an organism have different epigenomes that may change with time in ...

FISH

Biology; Genetics

Fluorescent in situ hybridisation, a technique which can be used to detect and localise the presence or absence of specific DNA sequences on chromosomes.

Gene expression

Biology; Genetics

The process by which the information in the DNA sequence of a gene is transcribed into messenger RNA and translated into protein.

Genetic screening

Biology; Genetics

Carrying out a genetic test on a whole unselected population, or on all the members of a subset of the population (for example, people from a particular ethnic group, or pregnant women, or newborn ...

Genetic test

Biology; Genetics

A test to detect the presence or absence of, or change in, a particular gene or chromosome

Genome-wide association study (GWA or GWAS)

Biology; Genetics

A study in which specific genetic markers (usually SNPs) across the entire genome of multiple people are scanned in order to find genetic variations associated with disease. By comparing DNA samples ...

Genome-wide significance

Biology; Genetics

Statistical term indicating that a genetic association is probably real, rather than being a false positive. Due to the large number of SNPs tested simultaneously in GWAS, the usual statistical ...
