The effects of learning about one’s own genetic susceptibility to alcoholism: a randomized experiment

Abstract: conclusion:The first complete randomized experiment to examine the psychological and behavioral effects of receiving personalized genetic susceptibility information indicates some potential perils and benefits of direct-to-consumer genetic tests. 2013:15(2):132-138 Genet Med

“…For example, among people with elevated levels of depressive symptomatology, attributing one’s symptoms to neurochemical or genetic causes is associated with pessimistic expectations about the duration of one’s own depression (Lebowitz, Ahn, et al, 2013). Relatedly, individuals who were told that they carried a gene associated with alcoholism rated themselves as less able to avoid drinking alcohol, compared to individuals who were told that they did not carry such a gene (Dar-Nimrod, Zuckerman, & Duberstein, 2013). Biological explanations for generalized anxiety disorder also increased prognostic pessimism among people whose self-report suggested the presence of the condition (Lebowitz, Pyun, & Ahn, 2014).…”

“…La suma de este valor para todos los SNP considerados constituye la puntuación de riesgo poligénico de un individuo diana. Frank et al (2012) fueron los primeros en aplicar este método a dependencia de alcohol, a partir de 1.333 casos y 2.168 controles divididos al azar en muestras de descubrimiento y diana de igual tamaño. Usando un umbral de significación p < 0,5 en el GWAS de la muestra de descubrimiento (lo que equivalió a analizar los ~84.000 SNP independientes más significativos), encontraron una diferencia en la puntuación del riesgo poligénico entre casos y controles en la muestra diana en la dirección esperada (p = 1,28x10 -6 ).…”

“…La más obvia es la detección de variantes comunes asociadas al trastorno bajo estudio, empleando el criterio establecido de significación genómica (p < 5x10 -8 , equivalente a una corrección de Bonferroni para un millón de pruebas). En dependencia de alcohol, los GWAS han confirmado la implicación ya conocida de ALDH2 o la familia de ADH y han identificado unos pocos genes adicionales, como PECR o NKAIN1-SERINC2 (Frank et al, 2012;Treutlein et al, 2009;Zuo et al, 2013). La experiencia en otros trastornos complejos indica que estos estudios, que analizan menos de 2.000 pacientes y similar número de controles en la fase de GWAS, tienen una potencia muy reducida para identificar SNP de susceptibilidad, pues su efecto individual es muy pequeño (odds ratio < 1,25).…”

“…Genetic essentialist biases reduce perception of behavioral control among individuals who endorse them or are merely exposed to them (Dar-Nimrod and Heine 2011a, Dar-Nimrod and Lisandrelli 2012, Dar-Nimrod et al 2013). The Theory of Planned Behavior (Ajzen 1991) and the Self-Regulation Model (Leventhal et al 2003), two empirically supported behavioral theories utilized extensively in the health field (Trumbo and Harper 2013, Hartjes and Baumann 2012, Armitage and Conner 2001), predict that reduction in perceived behavioral control decreases the likelihood that a relevant behavior will be enacted.…”
