ASD is characterized by difficulties in social communication and social interaction, and by restricted and repetitive patterns of behavior. ASD pathogenic mechanism is suggested to be closely related to genetic factors. Recent exosome sequence analysis for ASD patients revealed many <i>de novo<\/i> mutations, with chromatin helicase DNA-binding protein 8 (Chd8) being the most frequent mutation site (1, 2, 3). <i>Chd8<\/i> is a remarkable gene for ASD research.<br \/>\nCHD8 is expressed not only in neuronal tissues but also in many other tissues and functions as an ATP-dependent chromatin remodeling factor in regulation of many gene expression. <i>Chd8<\/i> transcripts two alternative splice variants that encode a full-length CHD8L and a short-length CHD8S. Depositors (Dr. Nakayama) and his colleague developed two independent <i>Chd8<\/i> knockout mouse which deficient in both CHD8 isoforms (\u0394SL: RBRC09758) and only CHD8L (\u0394L: RBRC09759) (4). Both heterozygous mutant strains show ASD-like phenotypes, similar to findings with ASD patients. For example, <i>Chd8<\/i> mutant mice show characteristic behaviors such as increased anxiety, repetitive behaviors and abnormal social interaction. <i>Chd8<\/i> mutant mice also show macrocephaly and gastrointestinal defects, consistent with ASD patients with <i>Chd8<\/i> mutations (5). Moreover, gene expression pattern in <i>Chd8<\/i> mutant mouse brain is similar with that in ASD patient\u2019s brain. Thus, CHD8 haploinsufficient mutant mice is a highly reproducible models of ASD. <i>Chd8<\/i> mutant mice may be useful not only for pathogenic study but also for drug or therapeutic development.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<table width=\"700\">\n<tbody>\n<tr>\n<td style=\"border: 0px; background-color: #ffffff; text-align: right; white-space: nowrap;\" valign=\"top\">Depositor<\/td>\n<td style=\"border: 0px; background-color: #ffffff; text-align: center; white-space: nowrap;\" valign=\"top\">:<\/td>\n<td style=\"border: 0px; background-color: #ffffff; text-align: left; font-weight: bold;\" colspan=\"2\" valign=\"top\">Keiichi Nakayama, M.D., Ph.D.<br \/>\nDepartment of Molecular and Cellular Biology<br \/>\nMedical Institute of Bioregulation, Kyushu University<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 0px; background-color: #ffffff; text-align: right; white-space: nowrap;\" valign=\"top\">Strain name<\/td>\n<td style=\"border: 0px; background-color: #ffffff; text-align: center; white-space: nowrap;\" valign=\"top\">:<\/td>\n<td style=\"border: 0px; background-color: #ffffff; text-align: left; font-weight: bold;\" colspan=\"2\" valign=\"top\">B6;129P2-Chd8&lt;tm1Kei&gt;<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 0px; background-color: #ffffff; text-align: right; white-space: nowrap;\" valign=\"top\">RBRC No.<\/td>\n<td style=\"border: 0px; background-color: #ffffff; text-align: center; white-space: nowrap;\" valign=\"top\">:<\/td>\n<td style=\"border: 0px; background-color: #ffffff; text-align: left;\" colspan=\"2\" valign=\"top\">RBRC09758<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 0px; background-color: #ffffff; text-align: right; white-space: nowrap;\" valign=\"top\">Strain name<\/td>\n<td style=\"border: 0px; background-color: #ffffff; text-align: center; white-space: nowrap;\" valign=\"top\">:<\/td>\n<td style=\"border: 0px; background-color: #ffffff; text-align: left; font-weight: bold;\" colspan=\"2\" valign=\"top\">B6.129P2-Chd8&lt;tm2.1Kei&gt;<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 0px; background-color: #ffffff; text-align: right; white-space: nowrap;\" valign=\"top\">RBRC No.<\/td>\n<td style=\"border: 0px; background-color: #ffffff; text-align: center; white-space: nowrap;\" valign=\"top\">:<\/td>\n<td style=\"border: 0px; background-color: #ffffff; text-align: left;\" colspan=\"2\" valign=\"top\">RBRC09759<\/td>\n<\/tr>\n<tr>\n<td style=\"border: 0px; background-color: #ffffff; text-align: right; white-space: nowrap;\" rowspan=\"7\" valign=\"top\">References<\/td>\n<td style=\"border: 0px; background-color: #ffffff; text-align: center; white-space: nowrap;\" rowspan=\"7\" valign=\"top\">:<\/td>\n<td style=\"border: 0px; background-color: #ffffff; text-align: left;\" valign=\"top\">[1]<\/td>\n<td style=\"border: 0px; background-color: #ffffff; text-align: left;\" valign=\"top\">O&#8217;Roak BJ, Vives L, Girirajan S, Karakoc E, Krumm N, Coe BP, Levy R, Ko A, Lee C, Smith JD, Turner EH, Stanaway IB, Vernot B, Malig M, Baker C, Reilly B, Akey JM, Borenstein E, Rieder MJ, Nickerson DA, Bernier R, Shendure J, Eichler EE.
