    ### Instruction:
    Is Congenital bilateral absence of the vas deferens inherited ?
    ### Response:
    How is congenital bilateral absence of the vas deferens (CBAVD) inherited? When this condition is caused by mutations in the CFTR gene, it is inherited in an autosomal recessive pattern. This pattern of inheritance means that both copies of the gene in each cell have a mutation.
