Your question: Can an autosomal dominant trait be carried by unaffected individuals?

Who can be a carrier for an autosomal trait?

If you are born to parents who both carry the same autosomal recessive gene, you have a 1 in 4 chance of inheriting the abnormal gene from both parents and developing the disease. You have a 50% (1 in 2) chance of inheriting one abnormal gene. This would make you a carrier.

What are autosomal diseases?

Autosomal disorders such as osteogenesis imperfecta (OI) are due to mutations in genes on the autosomes, or numbered chromosomes. Individuals have two copies (alleles) of every autosomal gene, one inherited from each parent. Autosomal dominant disorders are those that result from a mutation in one copy of the gene.
