About ONTIME


The Online Neurodegenerative Trait Integrative Multi-Omics Explorer (ONTIME) is a web-based catalogue of genome wide association studies dedicated to quantitative neurodegenerative disease endophenotypes. Users can search for associations to common and low-frequency variants by variant (by either rsID or chromosome:position on GRCh37), gene, endophenotype, or therapeutic category.


Currently, ONTIME contains summary statistics for 203 quantitative endophenotypes. Only associations for autosomes are displayed. Alleles (effect and non-effect) for each variant across all datasets have been aligned against those in dbSNP’s Human Build 150. Therefore, variants across all Manhattan plots display a standardized direction of effect. Summary statistics have also been filtered to remove variants without data for beta or p-value fields (eg, beta = NA).


ONTIME was built from the PheWeb code base. All genomic positions are on GRCh37. Summary statistics have been drawn from various sources, including the following published studies:
