These expressed peptides likely form epitopes which structurally mimic in vivo antigens (mimotopes) and showed partial homology to proteins which might be implicated in brain disorders (e.g. ras/Rap GTPase-activating protein (SYNGAP1), to different known proteins (e.g. zinc finger protein 148 (ZN148) and receptor tyrosine-protein phosphatase eta (PTPRJ)) and to proteins with unknown function (e.g. transmembrane protein 236 (TMEM236)) [25]. Here, SYNGAP1 is linked to brain disorder.
