Two remaining candidate genes under adaptive introgression in FRDs after Bonferroni correction are HTR2A and RYR3, which are involved in calcium signalling, affect neurobiological processes and are associated with behavioural disorders in humans and other mammals (Matsuo et al., 2009; Serretti et al., 2007; Table 3). This evidence concerns the gene RYR3 and Atypical behavior.
