Targeted Allele Detail
Symbol: Kcnq1tm2Kpfe
Name: potassium voltage-gated channel, subfamily Q, member 1; targeted mutation 2, Karl Pfeifer
MGI ID: MGI:3056648
Synonyms: Kcnq1T311I
Gene: Kcnq1  Location: Chr7:143106362-143427042 bp, + strand  Genetic Position: Chr7, 88.12 cM
Germline Transmission:  Earliest citation of germline transmission: J:93197
Parent Cell Line:  R1 (ES Cell)
Strain of Origin:  (129X1/SvJ x 129S1/Sv)F1-Kitl+
Allele Type:    Targeted (Inserted expressed sequence, Null/knockout)
Mutation:    Single point mutation
Mutation detailsA C to T transition resulting in an amino acid change of T311I was introduced in exon 7 via homologous recombination. Northern analysis showed that RNA is expressed at wild-type levels. Sequencing of amplified cDNA confirmed presence of the mutation. (J:93197)
