Question: Is Stickler syndrome inherited ?
Answer: Stickler syndrome types I, II, and III are 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 a gene mutation from one affected parent. Other cases result from new mutations. These cases occur in people with no history of Stickler syndrome in their family. Marshall syndrome also typically has an autosomal dominant pattern of inheritance. Stickler syndrome types IV, V, and VI are inherited in an autosomal recessive pattern. Autosomal recessive inheritance means both copies of the 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.
