Genome Sequence of the Pea Aphid \u3ci\u3eAcyrthosiphon pisum\u3c/i\u3e
Aphids are important agricultural pests and also biological models for studies of insect-plant interactions, symbiosis, virus vectoring, and the developmental causes of extreme phenotypic plasticity. Here we present the 464 Mb draft genome assembly of the pea aphid Acyrthosiphon pisum. This first published whole genome sequence of a basal hemimetabolous insect provides an outgroup to the multiple published genomes of holometabolous insects. Pea aphids are host-plant specialists, they can reproduce both sexually and asexually, and they have coevolved with an obligate bacterial symbiont. Here we highlight findings from whole genome analysis that may be related to these unusual biological features. These findings include discovery of extensive gene duplication in more than 2000 gene families as well as loss of evolutionarily conserved genes. Gene family expansions relative to other published genomes include genes involved in chromatin modification, miRNA synthesis, and sugar transport. Gene losses include genes central to the IMD immune pathway, selenoprotein utilization, purine salvage, and the entire urea cycle. The pea aphid genome reveals that only a limited number of genes have been acquired from bacteria; thus the reduced gene count of Buchnera does not reflect gene transfer to the host genome. The inventory of metabolic genes in the pea aphid genome suggests that there is extensive metabolite exchange between the aphid and Buchnera, including sharing of amino acid biosynthesis between the aphid and Buchnera. The pea aphid genome provides a foundation for post-genomic studies of fundamental biological questions and applied agricultural problems

Interrogating the Genetic Determinants of Touretteās Syndrome and Other Tic Disorders Through Genome-Wide Association Studies
Objective:
Touretteās syndrome is polygenic and highly heritable. Genome-wide association study (GWAS) approaches are useful for interrogating the genetic architecture and determinants of Touretteās syndrome and other tic disorders. The authors conducted a GWAS meta-analysis and probed aggregated Touretteās syndrome polygenic risk to test whether Touretteās and related tic disorders have an underlying shared genetic etiology and whether Touretteās polygenic risk scores correlate with worst-ever tic severity and may represent a potential predictor of disease severity. Methods:
GWAS meta-analysis, gene-based association, and genetic enrichment analyses were conducted in 4,819 Touretteās syndrome case subjects and 9,488 control subjects. Replication of top loci was conducted in an independent population-based sample (706 case subjects, 6,068 control subjects). Relationships between Touretteās polygenic risk scores (PRSs), other tic disorders, ascertainment, and tic severity were examined. Results:
GWAS and gene-based analyses identified one genome-wide significant locus within FLT3 on chromosome 13, rs2504235, although this association was not replicated in the population-based sample. Genetic variants spanning evolutionarily conserved regions significantly explained 92.4% of Touretteās syndrome heritability. Touretteās-associated genes were significantly preferentially expressed in dorsolateral prefrontal cortex. Touretteās PRS significantly predicted both Touretteās syndrome and tic spectrum disorders status in the population-based sample. Touretteās PRS also significantly correlated with worst-ever tic severity and was higher in case subjects with a family history of tics than in simplex case subjects. Conclusions:
Modulation of gene expression through noncoding variants, particularly within cortico-striatal circuits, is implicated as a fundamental mechanism in Touretteās syndrome pathogenesis. At a genetic level, tic disorders represent a continuous spectrum of disease, supporting the unification of Touretteās syndrome and other tic disorders in future diagnostic schemata. Touretteās PRSs derived from sufficiently large samples may be useful in the future for predicting conversion of transient tics to chronic tic disorders, as well as tic persistence and lifetime tic severity
