PRC-20199565-Overview

Perspectiva general

Genetic testing involves examining your DNA, the chemical database that carries instructions for your body's functions. Genetic testing can reveal changes (mutations) in your genes that may cause illness or disease.

Although genetic testing can provide important information for diagnosing, treating and preventing illness, there are limitations. For example, if you're a healthy person, a positive result from genetic testing doesn't always mean you will develop a disease. On the other hand, in some situations, a negative result doesn't guarantee that you won't have a certain disorder.

Talking to your doctor, a medical geneticist or a genetic counselor about what you will do with the results is an important step in the process of genetic testing.

Secuenciación del genoma

Cuando las pruebas genéticas no sirven para dar un diagnóstico, pero aún hay sospechas de una causa genética, algunos centros ofrecen una secuenciación del genoma, un proceso para analizar una muestra de ADN de la sangre.

Todas las personas tienen un genoma único, compuesto por el ADN presente en todos sus genes. Este análisis complejo pueda ayudar a identificar variaciones genéticas que pueden estar relacionadas con la salud. Esta prueba se suele limitar únicamente al análisis de las partes del ADN que codifican proteínas, denominadas «exomas».
