Allelic variants in HTR3C show association with autism.
Article in American journal of medical genetics. Part B, Neuropsychiatric genetics : the official publication of the International Society of Psychiatric Genetics, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Autism spectrum disorders (ASDs) are severe neurodevelopmental disorders with a strong genetic component. Only a few predisposing genes have been identified so far. We have previously performed a genome-wide linkage screen for ASDs in Finnish families where the most significant linkage peak was identified at 3q25-27. Here, 11 positional and functionally relevant candidate genes at 3q25-27 were tested for association with autistic disorder. Genotypes of 125 single nucleotide polymorphisms (SNPs) were determined in 97 families with at least one individual affected with autistic disorder. The most significant association was observed using two non-synonymous SNPs in HTR3C, rs6766410 and rs6807362, both resulting in P = 0.0012 in family-based association analysis. In addition, the haplotype C-C corresponding to amino acids N163-A405 was overtransmitted to affected individuals (P = 0.006). Sequencing revealed no other variants in the coding region or splice sites of HTR3C. Based on the association analysis results in a previously identified linkage region, we propose that HTR3C represents a novel candidate locus for ASDs and should be tested in other populations.
