CA8 and neuroblastoma: To better understand how rs6471859 regulates alternative splicing of CA8-204 we developed two constructs (CA8-204G or CA8-204C) and transfected HEK293 (renal-derived, non-neuronal) and NBL (neuroblastoma, neuronal-derived) cell lines with pCMV-N-FLAG-tagged vectors coding for the naturally occurring CA8-204G transcript or CA8-204C produced by reversion mutation of CA8-204.
