Cómo los genes pueden causar enfermedades
Los seres humanos tienen más de 20 000 genes, y cada uno realiza una o algunas funciones específicas en el cuerpo. Un gen le indica al cuerpo cómo digerir la lactosa de la leche, otro le dice cómo construir huesos fuertes y otro evita que las células comiencen a multiplicarse sin control y se conviertan en cáncer. Como todos estos genes juntos son las instrucciones de construcción de nuestro cuerpo, un defecto en uno de ellos puede tener consecuencias graves para la salud.
A través de décadas de investigación genética, conocemos el código genético de cualquier gen humano sano/funcional. También hemos identificado que, en ciertas posiciones de un gen, algunas personas pueden tener una letra genética diferente a la suya. A estos puntos críticos los llamamos “variaciones genéticas” o simplemente “variantes”. En muchos casos, los estudios han demostrado que tener la letra genética “G” en una posición específica es saludable, mientras que tener la letra “A” en la misma posición interrumpe la función del gen y causa una enfermedad. Genopedia le permite ver estas variantes en los genes y resume todo lo que sabemos de la investigación científica sobre qué letras genéticas (genotipos) tienen consecuencias buenas o malas para su salud o sus rasgos.
