Los objetivos de este estudio son saber si los sujetos en riesgo eran conscientes de su riesgo del 50% para la polineuropatía amiloide familiar (PAF); conocer el valor del riesgo subjetivo; y comprender la asociación entre las características sociodemográficas y la percepción del riesgo y entre el riesgo real y la percepción subjetiva del riesgo. Se examinaron 174 sujetos con riesgo de PAF del 50%. 52,9% de los sujetos en riesgo eran conscientes de su condición de riesgo del 50%. El valor medio del riesgo subjetivo fue mayor y más cercano al 50% cuando los sujetos eran conscientes de su condición de riesgo del 50%. La educación se asoció a una mayor conciencia de estar al 50% de riesgo. Parece que la información sobre los conocimientos previos antes de realizar el asesoramiento genético aumenta el riesgo subjetivo.
