Who gets haemochromatosis and how?

Quick answerHaemochromatosis is an inherited condition. To be affected youmustreceiveafaultygenefromeachparent

More information - Contributed by Professor Martin Delatycki

Genes and haemochromatosisWehaveabout25,000pairsofgenes ineachcell. Haemochromatosisoccursduetoapersoninheritinggenefaultswhicharetechnicallycalledmutations.Faultsinanumberofdifferentgenescancausehaemochromatosis,butinAustraliamostpeoplewiththeconditionhaveitduetofaultsintheHFEgene.

Our genes come in pairs, one inherited from each parent. To havehaemochromatosisapersonneeds tohavea fault inbothof theirHFEgenes(seefigure).Thisisknownasautosomalrecessiveinheritance.

General symptoms of iron overload

Fatigue,weakness,lethargy,apathy,weightloss,abdominalpainandjointaches.

Symptoms of higher levels of iron overload in certain organs

LiverIron overload in the liver causes fibrosis, which generally repairs whenironstoresarereduced.Higherlevelsofironleadtocirrhosis(irreversiblescarringandthedeathoflivercells).

Symptomsinclude:• Painintheliver(underyourrightribcage)duetoliverdamage• Enlargedliver,whichdoctorscallhepatomegaly• Fatigueandweakness• Jaundice(yellownessoftheskinandwhitesoftheeyes)• Reducedbodyhair,itching,easybruisingInthemostseriouscasesironoverloadleadstolivercancer.

Diabetes,ifuntreated,maycausesevereillnessincludingblindness,kidneyfailure,heartattackanddeath.

JointsHaemochromatosis is associated with arthritis. The most commonlyaffectedjointsarethehands,wrists,shoulders,hips,kneesandankles.

SkinIronoverloadmaycausegreyorbronzediscolourationoftheskin.

SexorgansIronoverloadmaycause:• Inwomen,irregularperiods,earlymenopause,lossoflibido• In men, impotence (inability to get or maintain an erection), loss

of libido, shrinking testicles (which doctors call testicular atrophy),developmentofmanboobs(whichdoctorscallgynaecomastia).


Will it happen to me?
