    Is common variable immune deficiency inherited ?
    ### Response:
    Most cases of CVID are sporadic and occur in people with no apparent history of the disorder in their family. These cases probably result from a complex interaction of environmental and genetic factors.  In some families, CVID is inherited in an autosomal recessive pattern, which means both copies of a gene in each cell have mutations.
