    ### Response:
    Autosomal recessive PKD is a rare genetic disorder that affects the liver as well as the kidneys. The signs of autosomal recessive PKD frequently appear in the earliest months of life, even in the womb, so health care providers often call it infantile PKD. In an autosomal recessive disorder, the child has to inherit the gene mutation from both parents to have an increased likelihood for the disorder.
