Targeted Allele Detail
Symbol: Gbatm1Nsb
Name: glucosidase, beta, acid; targeted mutation 1, Edward Ginns
MGI ID: MGI:1857175
Gene: Gba  Location: Chr3:89110223-89116180 bp, + strand  Genetic Position: Chr3, 39.01 cM
Alliance: Gbatm1Nsb page
Germline Transmission:  Earliest citation of germline transmission: J:1100
Parent Cell Line:  CCE/EK.CCE (ES Cell)
Strain of Origin:  129S/SvEv-Gpi1c
Allele Type:    Targeted (Null/knockout)
Mutation:    Insertion
Mutation detailsA neomycin resistance cassette was inserted into exons 9 and 10 of the gene, which encode part of the active site of the enzyme. Enzymatic activity of the targeted protein in homozygous mutant mice was less than 4% of controls. (J:1100)

Homozygotes for the mutation die within 24 hours after birth, and store glucocerebroside in reticuloendothelial cell lysosomes (J:1100). Epidermal effects of Gbatm1Nsb include elevated glucosylceremide, diminished ceremide, and incompetent barrier function (J:17577).
