LPL and Alzheimer disease: When the individual frequencies of LPL variants were compared between groups, we noticed that the p.N291S variant allele was significantly more common in AD than in control children (0.045 vs. 0.006; p = 0.010) while, at the opposite, the p.S447* allele tended to be more prevalent in controls than in AD children (respectively 0.126 vs. 0.064, p = 0.082).
