For congenital deafness and congenital blindness, the probability of onset can only be calculated based on genetic rules. For example, hereditary congenital deafness often has a family history of inheritance, and the probability of onset of the disease in its offspring is 25% to 50%. The greater the number of people in a family with the disease, the higher the incidence in offspring.
