Is keratitis-ichthyosis-deafness syndrome inherited ?
KID syndrome is usually inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. In some cases, an affected person inherits the mutation from one affected parent. However, most cases result from new mutations in the gene and occur in people with no history of the disorder in their family.  A few families have had a condition resembling KID syndrome with an autosomal recessive pattern of inheritance. In autosomal recessive inheritance, both copies of a gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition. Affected individuals in these families have liver disease, which is not a feature of the autosomal dominant form. The autosomal recessive condition is sometimes called Desmons syndrome. It is unknown whether it is also caused by GJB2 gene mutations.
