Symbol: Tg(FXN)YG22Pook
Name: transgene insertion YG22, Mark A Pook
MGI ID: MGI:4412181
Synonyms: YG22
Transgene: Tg(FXN)YG22Pook  Location: unknown  
Alliance: Tg(FXN)YG22Pook page
Strain of Origin:  CBA x C57BL/6
Transgene Type:    Transgenic (Humanized sequence, Inserted expressed sequence)
Mutation:    Insertion
Tg(FXN)YG22Pook expresses 1 gene
Mutation detailsThe transgenic construct consists of a 370kb YAC insert that includes the entire human FXN gene with GAA triplet repeat sequences, and was injected into fertilized CBA X C57BL/6 hybrid fertilized oocytes. Founder line YG22 was generated, showing a reduced transmission rate of 21%, indicating germ-line mosaicism of the transgene, compared to 52% transmission to offspring for founder line YG8. One copy of the FXN gene was detected, and contains a single 190 GAA repeat sequence. (J:91581)
