Gene: Chrne  Location: Chr11:70505709-70510042 bp, - strand  Genetic Position: Chr11, 43.14 cM
Alliance: Chrnetm1Vwi page
Germline Transmission:  Earliest citation of germline transmission: J:36557
Parent Cell Line:  E14.1 (ES Cell)
Strain of Origin:  129P2/OlaHsd
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsA genomic fragment containing part of exon 7 and exon 8 was replaced with a neomycin selection cassette. These sequences encode essential regions for the function of the protien. RT-PCR experiments on RNA derived from muscle tissue of homozygous mice demonstrated that no detectable levels of wild-type transcript were produced from this allele. (J:36557)
