β-Glucocerebrosidase (also called acid β-glucosidase, D-glucosyl-N-acylsphingosine glucohydrolase, or GCase) is an enzyme with glucosylceramidase activity (EC 3.2.1.45) that cleaves by hydrolysis the β-glycosidic linkage of the chemical glucocerebroside, an intermediate in glycolipid metabolism that is abundant in cell membranes (particularly skin cells).

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.
Mutation Research is a peer-reviewed scientific journal that publishes research papers in the area of mutation research which focus on fundamental mechanisms underlying the phenotypic and genotypic expression of genetic damage. There are currently three sections: Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis
There are several methods, or forms, of mutation that exist including spontaneous mutation, errors during replication and repair, as well as mutation due to environmental effects. [8] These origins of mutations can cause many different types of mutations which influence gene expression on both large and small scales.
The 96 mutation types concept from Alexandrov et al. [4] Considering the 5' flanking base (A, C, G, T), the 6 substitution classes (C>A, C>G, C>T, T>A, T>C, T>G) and 3' flanking base (A, C, G, T) leads to a 96 mutation types classification (4 x 6 x 4 = 96). The 16 possible mutation types of the substitution class C>A are shown as an example ...
A human disease modifier gene is a modifier gene [1] [2] that alters expression of a human gene at another locus that in turn causes a genetic disease.Whereas medical genetics has tended to distinguish between monogenic traits, governed by simple, Mendelian inheritance, and quantitative traits, with cumulative, multifactorial causes, increasing evidence suggests that human diseases exist on a ...
Ashley Dedmon is the author of the "The Big Family Trip" a children's book about discussing family medical history. Learn what inspired Dedmon to write it. Mom writes another children's book after ...
Occurrence of this phenomenon not only can result in major phenotypic changes but also reveal the expression of otherwise lethal genetic mutations. [3] Genetic mutations involved in mosaicism may be due to endogenous factors, such as transposons and ploidy changes, or exogenous factors, such as UV radiation and nicotine. [4]
