This condition is inherited in an autosomal dominant manner.

Hypertension and brachydactyly syndrome (HTNB), also known as Bilginturan syndrome and brachydactyly type E among others, is a very rare genetic disorder.[1][2]

It was first reported in 1973 by N. Bilginturan et al.[3][4] The estimated prevalence is less than 1 out of 1,000,000.[2]

Symptoms

The disorder is characterized by:

  • severe salt-independent but age-dependent hypertension
  • brachydactyly malformations of the hands and fingers
  • increased fibroblast growth rate
  • neurovascular contact at the rostral-ventrolateral medulla
  • altered baroreflex blood pressure regulation
  • death from stroke before age 50 years when untreated

Genetics

The disorder is thought to be related to mutations in the PDE3A gene.[1][5]
