Los autores, del Technion-Israel Institute of Technology, explican en "JACC" que existen dos formas del gen, las cuales están presentes en proporción similar en población general e individuos diabéticos. Sin embargo, los afectados por esta enfermedad que son portadores de un tipo del gen tienen cinco veces más probabilidades de desarrollar enfermedad cardíaca que los portadores del otro tipo.
En su estudio se realizaron pruebas genéticas a 206 individuos con enfermedad cardíaca y a 206 controles. El gen en cuestión es el de la haptoglobina, proteína de la sangre que se encuentra en tres formas distintas: 2-2, 1-1 y 2-1. Los individuos diabéticos con la forma 2-2 tienen cinco veces más riesgo de cardiopatía que los portadores de la forma 1-1. La forma 2-1 supone un riesgo intermedio.
"Si pudiéramos determinar con precisión qué personas con diabetes presentan mayor riesgo de enfermedad cardíaca con un test genético, se podrían salvar muchas vidas con técnicas de intervención precoces", afirman los autores.
