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).

Gaucher's disease or Gaucher disease (/ ɡ oʊ ˈ ʃ eɪ /) (GD) is a genetic disorder in which glucocerebroside (a sphingolipid, also known as glucosylceramide) accumulates in cells and certain organs.
The GBA gene encodes for glucocerebrosidase (GCase) which is a lysosomal enzyme that breaks down glucosylceramide into glucose. In the context of Parkinson's, mutations in GBA occur at a higher frequency than other genes indicated in PD.
Gaucher disease is caused by mutations in GBA1, which encodes the lysosomal catalyst glucocerebrosidase (GCase). GBA1 transformations drive broad gathering of glucosylceramide (GC) in different natural and versatile resistant cells in the spleen, liver, lung and bone marrow, frequently prompting endless irritation.
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 bias refers to a predictable or systematic difference in rates for different types of mutation.The types are most often defined by the molecular nature of the mutational change, but sometimes they are based on downstream effects, e.g., Ostrow, et al. [1] refer to "mutational bias for body size".
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:
A germline mutation in the reproductive cells of an individual gives rise to a constitutional mutation in the offspring, that is, a mutation that is present in every cell. A constitutional mutation can also occur very soon after fertilization , or continue from a previous constitutional mutation in a parent. [ 90 ]
