MGI ID: MGI:6286225
Synonyms: Nkx2.5R141C
Gene: Nkx2-5  Location: Chr17:27057638-27063962 bp, - strand  Genetic Position: Chr17, 13.6 cM
Germline Transmission:  Earliest citation of germline transmission: J:251389
Parent Cell Line:  R1 (ES Cell)
Strain of Origin:  (129X1/SvJ x 129S1/Sv)F1-Kitl+
Allele Type:    Targeted (Epitope tag, Humanized sequence)
Mutation:    Single point mutation
Mutation detailsExon 2 was replaced with one containing a CGC to TGC non-synonymous substitution resulting in an arginine to cysteine change at amino acid 141 (R141C), an frt-loxP-neo-frt-loxP cassette was inserted upstream of exon 2, and a flag tag was inserted at the ATG of exon 1. Flp-mediated recombination removed the neo selection cassette. This mutation is identified in patients with congenital heart defects. (J:251389)
