It's also discouraging that they support their finding by saying "The significant replicated association of Neandertal SNPs with mood disorders, in particular depression, is intriguing because Neandertal alleles are enriched near genes associated with long-term depression (5)". "Long-term depression" (LTD) has absolutely nothing to do with "depression". LTD is a mechanism of synaptic plasticity, where the strength of the synapse is reduced ("depressed"). I'm a neuroscientist, and I checked ref 5.
