FIELD: biotechnology.SUBSTANCE: invention relates to the field of biotechnology, in particular to a rodent containing a sequence characterized in expansion of hexanucleotide repeats at endogen locus C9orf72, as well as to its cell, embryo and motor neuron. An immortalized cell line containing a sequence characterized in expansion of hexanucleotide repeats at endogen locus C9orf72 is also disclosed. The invention also relates to a method for obtaining the above-mentioned rodent, providing for modification of a rodent genome to contain a sequence characterized in expansion of hexanucleotide repeats at endogen locus C9orf72.EFFECT: invention is effective for identification of a candidate therapeutic agent for the treatment of a disease or condition associated with the presence of the sequence characterized in expansion of hexanucleotide repeats.52 cl, 12 dwg, 10 tbl, 5 ex |
