A person who carries a mutation in only one copy of a gene, but where a mutation in both copies of that gene is required to cause a genetic condition. The carrier is therefore usually unaffected by the genetic condition, but can transmit the mutated gene to their children, who will be affected if they have mutations in both copies of the gene.
