gene amplification

Medical; Human genome

1) A selective increase in the number of copies of a gene coding for a specific protein without a proportional increase in other genes. It occurs naturally via the excision of a ...

galactosylceramides

Medical; Human genome

Cerebrosides which contain as their polar head group a galactose moiety bound in glycosidic linkage to the hydroxyl group of ceramide. Their accumulation in tissue, due to a ...

flanking marker

Medical; Human genome

An identifiable, polymorphic region of DNA (i.e., marker) located to the side of a gene (i.e., flanking), as opposed to an intragenic marker which is located within the gene ...

goiter

Medical; Human genome

Enlargement of the thyroid gland.

fatty liver

Medical; Human genome

1) Lipid infiltration of the hepatic parenchymal cells resulting in a yellow-colored liver. The abnormal lipid accumulation is usually in the form of triglycerides, either as a ...

gene expression

Medical; Human genome

1) The process by which a gene's coded information is translated into the structures present and operating in the cell (either proteins or RNAs). 2) Gene expression is the ...

gene dosage

Medical; Human genome

The number of copies of a given gene present in a cell or nucleus. An increase in gene dosage can result in the formation of higher levels of gene product, provided that the gene ...
