Learn About Branchiootorenal Syndrome

What is the definition of Branchiootorenal Syndrome?

Branchiootorenal (BOR) syndrome is a condition that disrupts the development of tissues in the neck and causes malformations of the ears and kidneys. The signs and symptoms of this condition vary widely, even among members of the same family. Branchiootic (BO) syndrome includes many of the same features as BOR syndrome, but affected individuals do not have kidney abnormalities. The two conditions are otherwise so similar that researchers often consider them together (BOR/BO syndrome or branchiootorenal spectrum disorders).

What are the causes of Branchiootorenal Syndrome?

Mutations in three genes, EYA1, SIX1, and SIX5, have been reported in people with BOR/BO syndrome. About 40 percent of people with this condition have a mutation in the EYA1 gene. SIX1 gene mutations are a much less common cause of the disorder. SIX5 gene mutations have been found in a small number of people with BOR syndrome, although researchers question whether mutations in this gene cause the condition. Some affected individuals originally reported to have SIX5 gene mutations were later found to have EYA1 gene mutations as well, and researchers suspect that the EYA1 gene mutations may be the actual cause of the condition in these people.

How prevalent is Branchiootorenal Syndrome?

Researchers estimate that BOR/BO syndrome affects about 1 in 40,000 people.

Is Branchiootorenal Syndrome an inherited disorder?

BOR/BO syndrome is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. In about 90 percent of cases, an affected person inherits the mutation from one affected parent. The remaining cases result from new mutations in the gene and occur in people with no history of the disorder in their family.
