Rationale:
Whole exome sequencing is a new rapid and cost effective tool for the diagnosis of the epilepsies. Our primary aim was to assess the quality of reporting of WES. Secondary aims; to compare the quality of studies based on journal type if recent ACMG guidelines have made influenced reporting quality; if any outcome reporting biases exist.
Method:
We analysed studies of whole exome sequencing in epilepsy. We used a self-constructed benchmark to quantitatively analyse studies, explore retrospectively if reporting trends have changed.
Results:
A total of 307 studies was included. Reporting of data was heterogenous with poor reporting of diagnostic yield in 6% of studies, incidental findings in 11%, variants of undetermined significance in 19%. Predictors of poor reporting included: Journal type, proband status and case reports. Pairwise comparisons of genetics journals versus other journals using relative risks yielded significant differences in reporting of consanguinity status (RR 1.27 CI 1.04-1.55); variant filtering (RR 1.95 CI 1.41-2.7) and determination of pathogenicity (RR 1.35 CI 1.17-1.56).
Conclusion:
Reporting of WES data in the medical literature is heterogenous, making comparisons across studies difficult. Formal structured guidelines similar to the CONSORT guidelines are needed to address this issue further.
