What is a Hypomorphic mouse?

Glossary Term. Hypomorphic Mutation. MGI Glossary. Definition. A type of mutation in which the altered gene product possesses a reduced level of activity, or in which the wild-type gene product is expressed at a reduced level.

What causes Hypomorphic?

Hypomorphic mutations have been generated in eukaryotic cell systems by insertion of an antibiotic resistance gene into an intron10 or the 3′-untranslated region of a gene3.

What does Biallelic mean?

Listen to pronunciation. (BY-uh-LEE-lik) Of or pertaining to both alleles of a single gene (paternal and maternal). For example, biallelic mutation carriers have a mutation (not necessarily the same mutation) in both copies of a particular gene (a paternal and a maternal mutation).

What is a neomorphic allele?

Neomorph alleles produce an active product with a new, different function, something that the wild type allele doesn’t do. It can be either new expression (new tissue or time) or a mutation in the product to create a new function (additional substrate or new binding site), not present in the wild type product.

What is an Antimorph?

Definition of antimorph : a gene producing an effect opposite to that of the wild-type gene of the same locus.

What is Hypermorphic?

Adjective. hypermorphic (not comparable) (genetics, of a mutation) causing an increase in otherwise normal gene function.

Are Neomorphs dominant?

A neomorphic mutation causes a dominant gain of gene function that is different from the normal function. A neomorphic mutation can cause ectopic mRNA or protein expression, or new protein functions from altered protein structure.

What is Polyallelic?

Adjective. polyallelic (not comparable) (genetics) Having multiple alleles at a genetic locus.

What is Multiallelic?

A multiallelic site is a specific locus in a genome that contains three or more observed alleles, again counting the reference as one, and therefore allowing for two or more variant alleles.

What are the 3 types of gene mutation?

There are three types of DNA Mutations: base substitutions, deletions and insertions. Single base substitutions are called point mutations, recall the point mutation Glu —–> Val which causes sickle-cell disease. Point mutations are the most common type of mutation and there are two types.

Why is Haploinsufficiency dominant?

Haploinsufficiency describes the situation where having only a single functioning copy of a gene is not enough for normal function, so that loss-of-function mutations cause a dominant phenotype.

What is the White alien in alien Covenant?

The pale-white Neomorph is featured in Alien: Covenant. It was created through exposure to spores found growing on the Engineer homeworld.
