A human read of these two abstracts would indeed immediately detect MTNR1B as a phenotype for obesity, an identification the PubMed search engine failed to reveal, while the InfoCodex semantic engine was able to reconstruct it by integrating information distributed over the two documents even if the exact word “phenotype” never appears in relation to MTNR1B. Here, MTNR1B is linked to obesity due to melanocortin 4 receptor deficiency.
