A team of researchers at Linköping University in Sweden has identified two genomic regions and five candidate genes associated with dog’s human-directed social behaviors. Interestingly, four of these genes are also related to social behavior disorders in humans. The work by M.E. Persson et al is the first genome-wide study presenting candidate genomic regions for dog sociability and inter-species communication. Image credit: Freddie10. Dogs are...

Genomic location, organization and subexonic copy number variation of the MUC7 gene in the human reference genome: the gray bar indicates the chromosomal band where MUC7 resides; the zoomed-in version of the gene shows the two coding exons (thick blue bars), the UTR region at the 3’ and 5’ ends (thin blue bars) and intronic regions (blue line in-between exons). Start and end of the transcript are indicated by the numbers at each end. The different functional domains within the MUC7 protein are designated by different colors at the bottom of the panel.
