    Autism spectrum disorder (ASD) is caused by combined genetic and environmental factors. Genetic heritability in ASD is estimated as 60-90%, and genetic investigations have revealed many monogenic factors. We analyzed 405 patients with ASD using family-based exome sequencing to detect disease-causing single-nucleotide variants (SNVs), small insertions and deletions (indels), and copy number variations (CNVs) for molecular diagnoses. All candidate variants were validated by Sanger sequencing or quantitative polymerase chain reaction and were evaluated using the American College of Medical Genetics and Genomics/Association for Molecular Pathology guidelines for molecular diagnosis. We identified 55 disease-causing SNVs/indels in 53 affected individuals and 13 disease-causing CNVs in 13 affected individuals, achieving a molecular diagnosis in 66 of 405 affected individuals (16.3%). Among the 55 disease-causing SNVs/indels, 51 occurred de novo, 2 were compound heterozygous (in one patient), and 2 were X-linked hemizygous variants inherited from unaffected mothers. The molecular diagnosis rate in females was significantly higher than that in males. We analyzed affected sibling cases of 24 quads and 2 quintets, but only one pair of siblings shared an identical pathogenic variant. Notably, there was a higher molecular diagnostic rate in simplex cases than in multiplex families. Our simulation indicated that the diagnostic yield is increasing by 0.63% (range 0-2.5%) per year. Based on our simple simulation, diagnostic yield is improving over time. Thus, periodical reevaluation of ES data should be strongly encouraged in undiagnosed ASD patients.

    Abstract

    Autism spectrum disorder (ASD) is a highly heritable, complex disorder in which rare variants contribute significantly to disease risk. Although many genes have been associated with ASD, there have been few genetic studies of ASD in the Japanese population. In whole exomes from a Japanese ASD sample of 309 cases and 299 controls, rare variants were associated with ASD within specific neurodevelopmental gene sets, including highly constrained genes, fragile X mental retardation protein target genes, and genes involved in synaptic function, with the strongest enrichment in trans-synaptic signaling (p = 4.4 × 10<sup>−4</sup>, Q-value = 0.06). In particular, we strengthen the evidence regarding the role of ABCA13, a synaptic function-related gene, in Japanese ASD. The overall results of this case-control exome study showed that rare variants related to synaptic function are associated with ASD susceptibility in the Japanese population.

  • A systematic review and network meta‐analysis of antimanic drugs for the treatment of acute mania used in Japan Reviewed

    Abstract

    This review aimed to clarify whether antimanic agents used in Japan are superior to placebo for the treatment of acute mania, based on reports of randomized controlled trials (RCTs) conducted in Japan and other East Asian countries. A literature search was conducted using the MEDLINE, PubMed, and Ichushi databases from their dates of inception to July 31, 2021, for studies written in English or Japanese with a primary diagnosis of bipolar I disorder, comparing any of the following active drugs to treat acute mania in adults: aripiprazole, carbamazepine, chlorpromazine, haloperidol, lithium, olanzapine, sultopride, timiperone, and zotepine. A random‐effects network meta‐analysis was performed within a frequentist framework. The quality of each included study was evaluated using the revised Cochrane risk‐of‐bias tool for randomized trials. The outcomes adopted were the response rate for efficacy and dropout rate for tolerability during 3 weeks from baseline. Eleven RCTs, totaling 1148 participants, were reviewed. The pooled odds ratio (OR) (±95% confidence interval [CI]) was calculated. Timiperone (OR = 4.53, CI 1.09–18.80), sultopride (OR = 3.76, CI 1.08–13.05), and aripiprazole (OR = 1.99, CI 1.22–3.24) were significantly more effective than placebo. Olanzapine (OR = 0.51, CI 0.29–0.90) was significantly superior in acceptability to placebo. The results showed no significant differences from placebo for carbamazepine, chlorpromazine, haloperidol, lithium, and olanzapine. These results suggest that noninferiority trials alone cannot always confirm the antimanic drug efficacy and that direct placebo‐controlled trials are necessary to verify the antimanic efficacy of the drugs.

    Background

    Most sequencing studies of schizophrenia (SCZ) have focused on de novo genetic variants due to interpretability. However, investigating shared rare variants among patients in the same multiplex family is also important. Relatively large-scale analyses of SCZ multiplex families have been done in Caucasian populations, but whether detected variants are also pathogenic in the Japanese population is unclear because of ethnic differences in rare variants.

    Materials and methods

    We performed whole-exome sequencing (WES) of 14 Japanese SCZ multiplex families. After quality control and filtering, we identified rare variants shared among affected persons within the same family. A gene ontology (GO) analysis was performed to identify gene categories possibly affected by these candidate variants.

    Results

    We found 530 variants in 486 genes as potential candidate variants from the 14 SCZ multiplex families examined. The GO analysis demonstrated significant enrichment in calcium channel activity.

    Conclusion

    This study provides supporting evidence that calcium ion channel activity is involved in SCZ. WES of multiplex families is a potential means of identifying disease-associated rare variants for SCZ.

    小児の社会機能低下に及ぼす親の抑うつの影響を明らかにすることを目的に、児童精神科外来を受診した児10症例(男児3例、女児7例、平均年齢11.7±2.2歳)とその親を対象に、児の社会機能については社会的職業的機能評定尺度の構造化評価システムを、親の抑うつについてはベック抑うつ質問票(BDI)をそれぞれ用いて評価した。その結果、親の抑うつについてはBDI 31点以上の重度のうつ状態、もしくは30分以上の時間をかけても全21項目への回答が選択できない状態が多く見られた。今回の結果から、小児の社会機能低下と親の抑うつは必ずしも関連付けられない可能性が示唆され、小児期以前の乳幼児期からの継続的な社会機能と親の抑うつの関連を明らかにする必要があると考えられた。
