While findings were less robust, genome-wide associations were also observed among intergenic chromosome 18 variant rs151174000 with parieto-frontal low theta coherence, chromosome 1 variant rs14429078 with parieto-occipital interhemispheric high theta coherence, and chromosome 4 variant rs116445911 with centro-parietal low theta coherence. While not much is known about these variants, rs116445911 is associated with the expression of SLC9B1 in brain69, and SLC9B1 has been associated with schizophrenia70, another neuropsychiatric disorder characterized by dysregulated neural connectivity71. As noted above, only a single variant was implicated for both rs144290781 and rs151174000, suggesting that these associations may be spurious.
