Targeted Allele Detail
Symbol: Snrpntm3Alb
Name: small nuclear ribonucleoprotein N; targeted mutation 3, Arthur L Beaudet
MGI ID: MGI:2384045
Gene: Snrpn  Location: Chr7:59982495-60140219 bp, - strand  Genetic Position: Chr7, 34.04 cM
Germline Transmission:  Earliest citation of germline transmission: J:56617
Parent Cell Line:  AB2.2 (ES Cell)
Strain of Origin:  129S7/SvEvBrd-Hprtb-m2
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsA 6 kb region of the gene encompassing exon 2 was replaced with an HPRT-loxP-neo cassette via homologous recombination resulting in deletion of 32 amino acids from the smaller of 2 open reading frames. The larger downstream open reading frame remains intact. RT-PCR analysis of heterozygous mutant animals showed expression of only wild-type transcripts in mice carrying a maternally derived mutation, and in mice carrying a paternally derived mutation the mutant transcript and transcripts of the neo gene are expressed. The deletion does not affect maternal-paternal imprinting of the DNA. (J:56617)
