Question: Is Cold agglutinin disease inherited ?
Answer: Is cold agglutinin disease inherited? Cold agglutinin disease is not an inherited condition. It is designated as either primary (unknown cause) or secondary (associated with or caused by another condition). In some cases, cold agglutinin may be multifactorial which means that multiple environmental factors and genes likely interact to predispose a person to developing the condition. However, to our knowledge, no disease-causing genes have been identified and no familial cases have been reported.
