Symbol: Hmbstm2Uam
Name: hydroxymethylbilane synthase; targeted mutation 2, Urs A Meyer
MGI ID: MGI:2182346
Synonyms: pbgdtm1(neo)Uam, T1
Gene: Hmbs  Location: Chr9:44336350-44344228 bp, - strand  Genetic Position: Chr9, 24.84 cM
Germline Transmission:  Earliest citation of germline transmission: J:31572

Strain of Origin:  C57BL/6J
Allele Type:    Targeted
Mutation:    Insertion
Mutation detailsThe insertion of a PGK-neo cassette disrupted exon 1, which is specific to isoforms transcribed in non-erythroid cells. RT-PCR analysis showed a lack of transcript containing exon 1, though the expression of a transcript consisting of exon 3 and downstream sequence was identified. The expression of this aberrant transcript was reported to be driven by the PGK promoter and was putatively responsible for the hepatic enzymatic activity determined in homozygous mutant mice (reduced by 44.7% from wild-type).
