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.
Segregating sites include conservative, semi-conservative and non-conservative mutations. The proportion of segregating sites within a gene is an important statistic in population genetics since it can be used to estimate mutation rate assuming no selection. For example it is used to calculate the Tajima's D neutral evolution statistic.
The 16 possible mutation types of the substitution class C>A are shown as an example. Once the mutation catalog (e.g. counts for each of the 96 mutation types) of a tumor is obtained, there are two approaches to decipher the contributions of different mutational signatures to tumor genomic landscape: The mutation catalog of the tumor is ...

Human somatic variations are somatic mutations (mutations that occur in somatic cells) both at early stages of development and in adult cells.These variations can lead either to pathogenic phenotypes or not, even if their function in healthy conditions is not completely clear yet.
[1] [4] [5] [7] [14] [16] [21] The addition of primers that are designed to be complementary to the ends of the extended fragments are added to further amplify the sequences with another PCR. [ 1 ] [ 14 ] [ 21 ] Primers may be chosen to have additional sequences added on to their 5’ ends, such as sequences for restriction enzyme recognition ...
Mutational robustness (also called mutation tolerance) describes the extent to which an organism's phenotype remains constant in spite of mutation. [9] Robustness can be empirically measured for several genomes [10] [11] and individual genes [12] by inducing mutations and measuring what proportion of mutants retain the same phenotype, function or fitness.
