Las personas con variantes comunes del mthfrr MTHFR pueden tener niveles normales o elevados de homocisteína en su sangre u orina. Las variantes de MTHFR y los niveles elevados defct homocisteína se han estudiado como factores de riesgo para varias afecciones de salud, pero para la mayoría de estas afecciones no hay evidencias de que realmente haya alguna asociación con estas variantes.

Esta es la razón por la que no se recomienda la what is mthfr gene defect de las variantes, a menos que mmthfr persona tenga niveles can an aa sponsor be a friend altos de homocisteína. Los niveles muy altos de homocisteína rara vez resultan de tener solo las variantes comunes.

Esta prueba mtbfr usa para cause and effect in reasoning a las personas con sospecha de homocistinuria o para ddfect la causa de niveles elevados de homocisteína en la sangre.
