![]() ![]() If the child only inherits one copy of the faulty gene, they'll be a carrier but won't have the condition. This means the condition can only be passed on to a child if both parents have a copy of the faulty gene – both are 'carriers' of the condition. Some conditions can only be inherited in an autosomal recessive pattern. ![]() These genetic conditions can be inherited in three main ways: Autosomal recessive inheritance Some medical conditions are directly caused by a mutation in a single gene that may have been passed on to a child by his or her parents. Genetic mutations occur when DNA changes, altering the genetic instructions. their environment, including any treatment they may get to prevent it. ![]() whether the gene for that condition is dominant (you only need one copy of the faulty gene to have the condition) or recessive (you need two copies of the faulty gene, if you only have one, you will be a carrier but you will not have the condition).Whether your child has a medical condition will depend on several factors, including: There are some medical conditions that are caused by genes, but most are caused by a combination of genes and environmental (life) factors. Our genes can also cause or increase the risk of developing some medical conditions. They determine things like our blood type, eye colour, hair and what our personalities will be like. These genes are a set of building blocks for our growth and development. Our genes contribute to our development as people, including our risk of having medical conditions. ![]()
