Is kabuki syndrome genetic? Kabuki syndrome is a rare genetic disorder with a range of characteristics, including intellectual disability, distinctive facial features and skeletal abnormalities. Estimates suggest that Kabuki syndrome occurs in about one in every 32,000 births.
How is Kabuki syndrome inherited? When Kabuki syndrome is caused by mutations in the KMT2D gene, 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 Kabuki syndrome is caused by mutations in the KDM6A gene, it is inherited in an X-linked dominant pattern .
How many cases of Kabuki syndrome are there? The incidence of Kabuki syndrome is unknown, but has been estimated to be somewhere between 1 in 32,000-86,000 individuals in the general population. More than 400 affected individuals who have genetically proven Kabuki syndrome have been reported in the medical literature.
Can Kabuki syndrome be detected before birth? Considering the AD transmission of the Kabuki it is of tremendous importance to identify if the parents are carriers or it is a de novo mutation. Prenatal diagnosis of the Kabuki syndrome cannot be made only on ultrasound signs that are not specific.

1. Today the average lifespan of a person with Down syndrome is approximately 60 years. As recently as 1983, the average lifespan of a person with Down syndrome was 25 years. The dramatic increase to 60 years is largely due to the end of the inhumane practice of institutionalizing people with Down syndrome.
