A Genetic Variant (COMT) Coding Dopaminergic Activity Predicts Personality Traits in Healthy Elderly.

Personality and individual differences

Kotyuk E, Duchek J, Head D, Szekely A, Goate AM, Balota DA.
PMID: 25960587
Pers Individ Dif. 2015 Aug 01;82:61-66. doi: 10.1016/j.paid.2015.03.012.

Association studies between the NEO five factor personality inventory and COMT rs4680 have focused on young adults and the results have been inconsistent. However, personality and cortical changes with age may put older adults in a more sensitive range...

Apolipoprotein E levels in cerebrospinal fluid and the effects of ABCA1 polymorphisms.

Molecular neurodegeneration

Wahrle SE, Shah AR, Fagan AM, Smemo S, Kauwe JS, Grupe A, Hinrichs A, Mayo K, Jiang H, Thal LJ, Goate AM, Holtzman DM.
PMID: 17430597
Mol Neurodegener. 2007 Apr 12;2:7. doi: 10.1186/1750-1326-2-7.

BACKGROUND: Animal studies suggest that brain apolipoprotein E (apoE) levels influence amyloid-beta (Abeta) deposition and thus risk for Alzheimer's disease (AD). We have previously demonstrated that deletion of the ATP-binding cassette A1 transporter (ABCA1) in mice causes dramatic reductions...
