• 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: Gba^tm1Nsb page

Mutation origin

• Germline Transmission: Earliest citation of germline transmission: J:1100
• Parent Cell Line: CCE/EK.CCE (ES Cell)
• Strain of Origin: 129S/SvEv-Gpi1^c

Mutation description

• Allele Type: Targeted (Null/knockout)
• Mutation: Insertion
• Mutation details: A 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)

Notes

Homozygotes for the mutation die within 24 hours after birth, and store glucocerebroside in reticuloendothelial cell lysosomes (J:1100). Epidermal effects of Gba^tm1Nsb include elevated glucosylceremide, diminished ceremide, and incompetent barrier function (J:17577).
