In about 10 percent of cases, a genetic cause for CVID is known. Mutations in at least 13 genes have been associated with CVID. The most frequent mutations occur in the TNFRSF13B gene. The protein produced from this gene plays a role in the survival and maturation of B cells and in the production of antibodies.
Genetic traits can be passed through families in several distinct patterns. The most common patterns are the following: 1  Dominant genetic diseases are caused by a mutation in one copy of a gene.2  If a parent has a dominant genetic disease, then each of that personâs children has a 50% chance of inheriting the disease. Dominant diseases can also occur spontaneously; this happens when a random mutation in one gene occurs at conception. 2  Examples of dominant genetic diseases include Achondroplasia and Huntington disease. 3  For some dominant genetic diseases, there may be specific DNA tests available. 4  Recessive genetic diseases.
