AS Genotype — What Sickle Cell Trait Means for You

AS means you carry one sickle gene and one normal one. You are generally healthy, your life expectancy is normal, and you do not have sickle cell disease.

You are a carrier, not a patient

AS means you carry one sickle gene and one normal one. You are generally healthy, your life expectancy is normal, and you do not have sickle cell disease.

When AS occasionally matters

Under extreme conditions — severe dehydration, very high altitude, extreme exertion without fluids — some people with AS experience symptoms. This is uncommon and avoidable with sensible hydration.

What it means for children

AS with AA is safe. AS with AS gives a 1-in-4 chance of SS per pregnancy. AS with SS gives 1-in-2.

You do not need treatment

AS requires no medication and no restriction on normal life, work or sport.
