SNP-based HLA allele tagging, imputation and association with antiepileptic drug-induced cutaneous reactions in Hong Kong Han Chinese.
Article in The pharmacogenomics journal, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Human leukocyte antigen (HLA) genes control the regulation of the human immune system and are involved in immune-related diseases. Population surveys on relationships between single nucleotide polymorphisms (SNP) and HLA alleles are essential to conduct genetic association between HLA variants and diseases. Samples were obtained from our in-house database for epilepsy genetics and pharmacogenetics research. Using 184 epilepsy patients with both genome-wide SNP array and HLA-A/B candidate gene sequencing data, we sought tagging SNPs that completely represent sixHLA risk alleles; in addition, a Hong Kong population-specific reference panel was constructed for SNP-based HLA imputation. The performance of our new panel was compared to a recent Han Chinese panel. Finally, genetic associations of HLA variants with mild skin rash were performed on the combined sample of 408 patients. Common SNPs rs2571375 and rs144295468 were found to successfully tag HLA risk alleles A*31:01 and B*13:01, respectively. HLA-B*15:02 can be predicted by rs144012689 with >95% sensitivity and specificity. The imputation reference panel for the Hong Kong population had comparable performance to the Han Chinese panel due to the large sample size for common HLA alleles, though it retained discordance for imputing rare alleles. No significant genetic associations were found between HLA genetic variants and mild skin rash induced by aromatic antiepileptic drugs. This study provides new information on the genetic structure of HLA regions in the Hong Kong population by identifying tagging SNPs and serving as a reference panel. Moreover, our comprehensive genetic analyses revealed no significant association between HLA alleles and mild skin rash in Hong Kong Han Chinese.
