Question: Is Klippel-Feil syndrome inherited ?
Answer: When Klippel-Feil syndrome is caused by mutations in the GDF6 or GDF3 genes, it is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. When caused by mutations in the MEOX1 gene, Klippel-Feil syndrome is inherited in an autosomal recessive pattern, which 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. As a feature of another disorder, Klippel-Feil syndrome is inherited in whatever pattern the other disorder follows.
