Symbol: Galnstm1Toma
Name: galactosamine (N-acetyl)-6-sulfate sulfatase; targeted mutation 1, Shunji Tomatsu
MGI ID: MGI:2686931
Synonyms: Galns-
Gene: Galns  Location: Chr8:122578238-122611487 bp, - strand  Genetic Position: Chr8, 71.91 cM
Germline Transmission:  Earliest citation of germline transmission: J:87155
Parent Cell Line:  Not Specified (ES Cell)
Strain of Origin:  129X1/SvJ
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsA 1.8 kb fragment encompassing portions of intron 1 and exon 2 was deleted via homologous and cre-mediated recombination. A single loxP site remained in place of the deleted region. Transcript was undetected in homozygous mutant mice by Northern blot and RT-PCR analyses. Furthermore, homozygous mutant mice showed no GALNS enzmye activity. (J:87155)
