Mutation detailsA floxed neo cassette that had replaced exons 7 and 8 was excised from Cln3tm1Mem via in vivo cre mediated recombination in the germline. Expression analyses showed the presence of various aberrantly splice transcripts. Translation of a cDNA derived from RT-PCR analysis produced a protein containing the amino and carboxyl terminals as well as a novel mid-section. BLASTN revealed homology with a protein isolated from a patient with the juvenile-onset form of neuronal ceroid lipofuscinosis (JNCL). (J:79615)
