[Genome] Annotation-confused

[Chandrashekara Mallappa]

Hi I am trying to clone CHD2 gene from mouse. As for as my knowledge goes
full length cDNA of this gene is never cloned. This gene is annotated to
have 6 exons and a transcript length of 739bp in Ensemble and the same gene
is annotated to have more than 25 exons with a transcript length of 5794bp
in NCBI and UCSC genome browser. It is very important for me to clone this
gene for my research. So please guide me about what transcript should I
consider...Thanks a lot for your time and help.
