mirDNMR is a database for the collection of gene-centered background DNMRs obtained from different methods and population variation data. The database has the following functions: (i) browse and search the background DNMRs of each gene predicted by four different methods, including GC content (DNMR-GC), sequence context (DNMR-SC), multiple factors (DNMR-MF) and local DNA methylation level (DNMR-DM); (ii) search variant frequencies in publicly available databases, including ExAC, ESP6500, UK10K, 1000G and dbSNP and (iii) investigate the DNM burden to prioritize candidate genes based on the four background DNMRs using three statistical methods (TADA, Binomial and Poisson test). In conclusion, mirDNMR can be widely used to identify the genetic basis of sporadic genetic diseases.

OKCAM (Ontology-based Knowledgebase for Cell Adhesion Molecules) is an online resource for human genes known or predicted to be related to the processes of cell adhesion. These genes include members of the cadherin, immunoglobulin/FibronectinIII (IgFn), integrin, neurexin, neuroligin, and catenin families.

Internal Control Genes (ICG) is a wiki-based knowledgebase of internal control genes (or reference genes) for RT-qPCR normalization in a variety of species across three domains of life. Based on community curation, ICG provides curated data from a large volume of literature and provides information on internal control genes corresponding to specific experimental conditions for both model and non-model organisms.

Indel Flanking Region Database is an online resource for indels (insertion/deletions) and the flanking regions of proteins in SCOP superfamilies. It aims at providing a comprehensive dataset for analyzing the qualities of amino acid indels, substitutions and the relationship between them.

FerrDb V2 contains 1001 ferroptosis regulators and 143 ferroptosis-disease associations manually curated from 3288 articles. Specifically, there are 621 gene regulators, of which 264 are drivers, 238 are suppressors, 9 are markers, and 110 are unclassified genes; and there are 380 substance regulators, with 201 inducers and 179 inhibitors. Compared to FerrDb V1, curated articles increase by > 300%, ferroptosis regulators increase by 175%, and ferroptosis-disease associations increase by 50.5%. Circular RNA and pseudogene are novel regulators in FerrDb V2, and the percentage of non-coding RNA increases from 7.3% to 13.6%. External gene-related data were integrated, enabling thought-provoking and gene-oriented analysis in FerrDb V2.

China National GeneBank DataBase (CNGBdb) is an official partner of the GISAID Initiative. It provides access to EpiCoV and features the most complete collection of hCoV-19 genome sequences along with related clinical and epidemiological data. With the data from this database scientific researchers can construct a virus phylogenetic tree to reveal the characteristics of the pathogen, and provide effective references for the study and analysis of the evolutionary source and pathological mechanism of the novel coronavirus.
