A SNP in the gene encoding lactase (LCT) (C/T-13910) is associated with the ability to digest milk as adults (lactase persistence) in Europeans, but the genetic basis of lactase persistence in Africans was previously unknown. We conducted a genotype-phenotype association study in 470 Tanzanians, Kenyans and Sudanese and identified three SNPs (G/C-14010,(More)
Understanding genetic variation and its functional consequences within cis-regulatory regions remains an important challenge in human genetics and evolution. Here, we present a fine-scale functional analysis of segregating variation within the cis-regulatory region of prodynorphin, a gene that encodes an endogenous opioid precursor with roles in cognition(More)
The Dysfunctional Attitude Scale (DAS) is an inventory of beliefs about life. These beliefs attribute happiness to external events and reflect absolute expectations for one's own behavior and that of others. Such beliefs, according to some cognitive theorists, predispose persons to depression. To test this theory, we administered the DAS to private(More)
Brain electrical activity mapping (BEAM) and personality disorder assessment (Millon Clinical Multiaxial Inventory-II) were performed on a married couple and their four children. Three of the children had previously been identified as having obsessive compulsive disorder (OCD). Temporal lobe abnormalities were found in all four children but in neither(More)
