Synonyms: Sca684Q
Gene: Cacna1a  Location: Chr8:84338639-84640246 bp, + strand  Genetic Position: Chr8, 40.95 cM
Germline Transmission:  Earliest citation of germline transmission: J:139488
Parent Cell Line:  Not Specified (ES Cell)
Strain of Origin:  129S/SvEv
Allele Type:    Targeted (Humanized sequence)
Mutations:    Insertion, Intragenic deletion, Nucleotide repeat expansion
Mutation detailsA floxed neo cassette was inserted upstream of exon 46 and exon 47 was replaced with its human equivalent. During the process the number of CAG repeats was modified to 84, and transient cre expression was used to remove the floxed neo cassette. (J:139488)
