“…In addition, multiple independent bioinformatics analyses such as network analysis have indicated PDHB as a potential key gene related to AD pathology [62] , [80] , [81] , [82] . As for NADSYN1, there are several pieces of evidence showing that genetic polymorphisms of NADSYN1 are associated with cognitive impairment [83] , [84] , [85] , [86] . Aberrant protein expression of NADSYN1 is also observed in cognitive impairment patients [87] .…”
