Four single nucleotide polymorphisms (SNPs) in PSP‐encoding gene were identified only in hippocampus samples from AD subjects (n = 11) and not in healthy controls (n = 10) (Table S1): two substitutions (rs78599516 and rs74445297) were missense and two (rs202027697 and rs199851385) synonymous (Table S1). The gene discussed is PSPH; the disease is Alzheimer disease.
