Hiperplasia suprarrenal congénita - Overview

Nombres alternativos

Síndrome genitosuprarrenal; Deficiencia de 21-hidroxilasa

Definición:

Se refiere a un grupo de trastornos hereditarios de las glándulas suprarrenales.

Causas, incidencia y factores de riesgo:

La hiperplasia suprarrenal congénita puede afectar tanto a los niños como a las niñas. Las personas que padecen esta afección carecen de una enzima requerida por la glándula suprarrenal para producir las hormonas cortisol y aldosterona.

Sin estas hormonas, el cuerpo produce más andrógenos, un tipo de hormona sexual masculina, lo cual ocasiona la aparición temprana (o inapropiada) de características masculinas.

Alrededor de 1 de cada 10.000 a 18.000 niños nacen con hiperplasia suprarrenal congénita.
