The ancestral allele is C. The rs7412(T) allele, also known as Arg176Cys, generally indicates the presence of an Apoε2 allele; see the ApoE page for a full discussion of the ApoE alleles and their association with Alzheimer's disease.
Another SNP related to ApoE is rs429358.
In a study of 67 mostly Caucasian patients prescribed the atypical antipsychotic olanzapine, carriers of a rs7412(C) allele were more likely to gain significant weight compared to rs7412(T;T) carriers, as assessed by physiogenomic analysis of corresponding weight profiles. Two other SNPs, rs5092 and rs4765623, were also significantly associated with weight profiles in these patients.[PMID 17199131][PMID 20406466] Genetic variants associated with fasting blood lipids in the U.S. population: Third National Health and Nutrition Examination Survey
