“…The consequence of demonstrating the presence of an HFE mutation in a patient with PCT is in itself not apparent, because PCT patients generally exhibit biochemical signs of iron overload. One study found that chloroquine is not as effective in C282Y homozygotes as in the other HFE genotypes, but the treatment of choice will be venesection in most cases, irrespective of the results of HFE testing (23 ).…”

“…La relación entre mutaciones HFE con los índices séricos férricos, la concentración férrica hepática y la fibrosis varía de unos trabajos a otros (2,4,16,18,25,26,28,30,31). En nuestra serie el 80% de los pacientes presentaron elevación de ferritina.…”

“…A presença destas mutações no gene HFE tem sido largamente estudada nos doentes com PCT que apresentam uma elevada frequência da mutação C282Y em homozigotia (entre 11 e 47% nos estudos realizados na maioria dos países da Europa e EUA) 3,4,12,13 . Um estudo no norte da Itália demonstrou também uma incidência significativamente aumentada da mutação H63D nos doentes com PCT 3,4,13,14 .…”

“…Um estudo no norte da Itália demonstrou também uma incidência significativamente aumentada da mutação H63D nos doentes com PCT 3,4,13,14 . O estudo destas mutações nos doentes com PCT para além de estar indicado para rastreio genético de hemocromatose hereditária, tem também implicações no tratamento desta doença.…”
