Homocistinuria - Información general

Nombres alternativos

Deficiencia de cistationina beta-sintasa

Definición:

Es un trastorno hereditario que afecta el metabolismo del aminoácido metionina.

Causas, incidencia y factores de riesgo:

La homocistinuria se hereda en familias como un rasgo autosómico recesivo, lo cual significa que el niño debe heredar el gen defectuoso de ambos padres para que resulte afectado seriamente.

La homocistinuria tiene varios rasgos comunes con el síndrome de Marfan. A diferencia del síndrome de Marfan, en el cual las articulaciones tienden a estar "flojas o sueltas", en la homocistinuria tienden a estar "rígidas".
