Synonyms: Chga-
Gene: Chga  Location: Chr12:102521228-102531287 bp, + strand  Genetic Position: Chr12, 51.66 cM
Germline Transmission:  Earliest citation of germline transmission: J:111025
Parent Cell Line:  R1 (ES Cell)
Strain of Origin:  (129X1/SvJ x 129S1/Sv)F1-Kitl+
Allele Type:    Targeted (Null/knockout)
