Symbol:	Hexatm1Grv
Name:	hexosaminidase A; targeted mutation 1, Roy A Gravel
MGI ID:	MGI:2429698
Synonyms:	Hexa -
Gene:	Hexa  Location: Chr9:59446966-59472392 bp, + strand  Genetic Position: Chr9, 32.02 cM
Alliance:	Hexatm1Grv page

Germline Transmission:	Earliest citation of germline transmission: J:30899
Parent Cell Line:	CGR8 (ES Cell)
Strain of Origin:	129P2/OlaHsd

Allele Type:    Targeted (Null/knockout) Mutation:    Insertion   Mutation details: Exon 11 was disrupted by the insertion of a neomycin selection cassette. Northern blot analysis of homozygous mutant mice showed an absence of normal transcript and the presence of an elongated transcript which contained neo sequence. Hydrolysis of 4-MUG-6-sulfate (MUGS) was reduced to less than 5% in homozygous mutant mice. (J:30899)
