RT Journal Article SR Electronic T1 Pheno4J: a gene to phenotype graph database JF bioRxiv FD Cold Spring Harbor Laboratory SP 142257 DO 10.1101/142257 A1 Sajid Mughal A1 Ismail Moghul A1 Jing Yu A1 Tristan Clark A1 David S Gregory A1 Nikolas Pontikos YR 2017 UL http://biorxiv.org/content/early/2017/05/25/142257.abstract AB Summary Efficient storage and querying of large amounts of genetic and phenotypic data is crucial to contemporary clinical genetic research. This introduces computational challenges for classical relational databases, due to the sparsity and sheer volume of the data. Our Java based solution loads annotated genetic variants and well phenotyped patients into a graph database to allow fast efficient storage and querying of large volumes of structured genetic and phenotypic data. This abstracts technical problems away and lets researchers focus on the science rather than the implementation. We have also developed an accompanying webserver with end-points to facilitate querying of the database.Availability and Implementation The Java code and python code is available at https://github.com/phenopolis/pheno4iContact n.pontikos{at}ucl.ac.uk
