Recent advances in epitranscriptomics have unveiled functional associations between RNA modifications and multiple human diseases but distinguishing the functional or disease-related SNVs from the majority of ‘silent’ variants remains a major challenge. We previously developed the RMDisease database for unveiling the association between genetics variants and RNA modifications concerning human disease pathogenesis. In this work, we present RMDisease v2.0, an updated database with expanded coverage. Using deep learning models and from 873,819 experimentally-validated RNA modification sites, we identified a total of 1,366,252 RNA modification (RM)-associated variants that may affect (add or remove RM site) 16 different types of RNA modification (m6A, m5C, m1A, m5U, Ψ, m6Am, m7G, A-to-I, ac4C, Am, Cm, Um, Gm, hm5C, D and f5C) in 20 organisms (human, mouse, rat, zebrafish, maize, fruit fly, yeast, fission yeast, Arabidopsis, rice, chicken, goat, sheep, pig, cow, rhesus monkey, tomato, chimpanzee, green monkey and COVID-19). Among them, 14,749 disease- and 2,441 trait-associated genetic variants may function via the perturbation of epitranscriptomic markers. RMDisease v2.0 should serve as a useful resource for studying the genetic drivers of phenotypes that lie within the epitranscriptome layer circuitry.
16 RNA modification types from 20 different species
In RMDisease v2.0, we collected the epitranscriptome profiles of 16 types of RNA modifications from 20 species, including m6A (589,290 sites), m5C (150,412), m1A (32,758), m5U (3,696), Ψ (7,032), m6Am (2,447), m7G (9,951), A-to-I (52,760), ac4C (14,266), Am (1,591), Cm (1,878), Um (2,253), Gm (1,471), hm5C (1,759), D (371) and f5C (1,892), respectively. Specifically, the various types of RNA modification sites were derived from 679 high-throughput sequencing samples by 21 sequencing techniques.RM-associated variants
RMDisease v2.0 contains a total of 1,366,252 genetic variants that may affect (add or remove) various types of RNA modification in multiple species. This represents a six-fold increase in RM-associated variants, as well as a significant expansion in covered species (from human only to 20 species) and type of RNA modification (from eight to 16 types), compared with our previous version. Specifically, RMDisease v2.0 hosts RM-associated variants related to m6A (833,196), m5C (72,484), m1A (97,104), m5U (14,586), Ψ (84,950), m6Am (15,436), m7G (24,049), A-to-I (71,367), ac4C (45,891), Am (21,806), Cm (24,437), Um (37,313), Gm (19,623), hm5C (49), D (17) and f5C (3,944), covering a variety of species in human (732,418), mouse (227,739), rat (1,752), zebrafish (11,752), maize (1,322), fruit fly (208), yeast (27,533), fission yeast (17), Arabidopsis (144,198), rice (10,438), chicken (14,679), goat (7,860), sheep (18,439), pig (25,484), cow (64,275), rhesus (2,442), tomato (64,830), chimpanzee (167), green monkey (137) and COVID-19 (10,562).

RMDisease V2.0 provides users with a browser page for 16 types of RNA modifications (m6A, m5C, m1A, m5U, Ψ, m6Am, m7G, A-to-I, ac4C, Am, Cm, Um, Gm, hm5C, D and f5C) in 20 species (human, mouse, rat, zebrafish, maize, fly, yeast, fission yeast, arabidopsis, rice, chicken, goat, sheep, pig, cow, rhesus, tomato, chimpanzee, green monkey and COVID-19). The detailed list of modified sites information is listed here. Users can filter the results with Gene Type. Users can also filter the results by their annotations: whether is protein binding region, miRNA target site, splicing site or not, whether it has known diseases, phenotype linkage integrated from GWAS or ClinVar and the type of trait. Due to the specific situations of different species, filter columns in second line are changed with species' change.

Pie chart shows the percentage of modification type, species and modification status. Bar chart illustrate the numbers of detected sites, gene, RBP, miRNA Target, Splicing Site, GWAS and ClinVar.# Search
RMDisease V2.0 provides users a combined selection function of several choices to query the various data which you are interested in. The first choice is to select the species of interest, e.g. Homo sapiens(human). The second choice is used to determine the searching approach, i.e. searching depending on Gene, Region, Rs ID, Disease or Trait.Example:
For example, after setting the Gene and Homo sapiens(human) choices, users can type in any letters to trigger the drop-down box correspondingly, and then select the gene which you want. Or you could directly type in a word, the query results will provide you all types of gene if human in RMDisease V2.0. Here you go!
