The APOE and Serotonin Transporter Alleles data product includes data for the APOE isoform, directly genotyped using a TaqMan allelic discrimination SNP assay, where available, or imputed from preexisting genotype array data otherwise. This file also includes human serotonin transporter (5HTTLPR) short and long alleles measured using polymerase chain reaction (PCR). In total, there are 19,193 HRS participants in the data file: 17,237 with directly genotyped data for APOE and 1,956 additional participants with imputed data. There are 17,364 participants with valid values for 5HTTLPR.

Provided in this dataset is a csv file containing APOE genotypes and HTTLPR calls for 19,193 total subjects. 17,237 subjects’ APOE genotypes were collected directly using a TaqMan allelic discrimination SNP assay at the Center for Inherited Disease Research (CIDR) Genetic Resources Core Facility (GRCF) and Fragment Analysis Facility (FAF) at Johns Hopkins University. 1,956 subjects’ APOE genotypes were imputed from a preexisting genotype array to the 1000G (Phase3 v5) reference panel. 17,364 subjects’ HTTLPR short and long alleles were measured using PCR.

For investigators using any data from this dataset:

Please cite/reference the use of NIAGADS data by including the accession NG00132.

For investigators using HRS (sa000021) data:

HRS is supported by the National Institute on Aging (NIA U01AG009740). The genotyping was partially funded by separate awards from NIA (RC2 AG036495 and RC4 AG039029). Our genotyping was conducted by the NIH Center for Inherited Disease Research (CIDR) at Johns Hopkins University. Genotyping quality control and final preparation were performed by the Genetics Coordinating Center at University of Washington (Phases 1-3) and the University of Michigan (Phase 4).
