How common is heterotaxy?

The prevalence of heterotaxy syndrome is estimated to be 1 in 10,000 people worldwide. However, researchers suspect that the condition is underdiagnosed, and so it may actually be more common than this. Heterotaxy syndrome accounts for approximately 3 percent of all congenital heart defects.

When does heterotaxy occur?

What are the causes of Pediatric Heterotaxy Syndrome? Heterotaxy syndrome develops before birth. It occurs in about one in 10,000 births and more boys than girls develop the condition.

What does the Tbx5 gene do?

The TBX5 gene provides instructions for making a protein called T-box 5 that plays an important role in the formation of tissues and organs during embryonic development. This protein regulates the activity of other genes by attaching (binding) to specific regions of DNA.

What are the causes of Holt Oram syndrome?

Holt-Oram syndrome is caused by genetic changes (pathogenic variants or mutations) in the TBX5 gene. The syndrome is inherited in an autosomal dominant manner. A diagnosis of Holt-Oram syndrome may be suspected when a person has symptoms of the syndrome.

How are wrist bones treated with Holt Oram syndrome?

Treatment of wrist bone and other upper limb bone problems may include corrective or reconstructive surgery, the use of limb prosthetics, and physical or occupational therapies. The goal of treatment is to help people with Holt-Oram syndrome have as much use of the upper limbs as possible.
