[PMID 17053149] In a Swiss cohort: "Carriers of KIBRA rs17070145 T allele had 24% better free recall performance 5 min after word presentation (P = 0.000004) and 19% better free recall performance 24 hours after word presentation (P = 0.0008) than did noncarriers."
In a US cohort: "T allele carriers had significantly better memory scores than non-carriers in the Buschke's Selective Reminding Test (SRT). Performance on another episodic memory task, the Rey Auditory Verbal Learning Test (AVLT), was also significantly different between allele groups." In another Swiss cohort, with a visual episodic memory task: "T allele carriers also performed significantly better than did noncarriers in this population." "Functional magnetic resonance imaging detected KIBRA allele-dependent differences in hippocampal activations during memory retrieval."
