Whole-exome sequencing and imaging genetics identify functional variants for rate of change in hippocampal volume in mild cognitive impairment

Whole-exome sequencing of individuals with mild cognitive impairment, combined with genotype imputation, was used to identify coding variants other than the apolipoprotein E (APOE) ɛ4 allele associated with rate of hippocampal volume loss using an extreme trait design. Matched unrelated APOE ɛ3 homo
