Disease Profile

Thoracolaryngopelvic dysplasia

Prevalence estimates on Rare Medical Network websites are calculated based on data available from numerous sources, including US and European government statistics, the NIH, Orphanet, and published epidemiologic studies. Rare disease population data is recognized to be highly variable, and based on a wide variety of source data and methodologies, so the prevalence data on this site should be assumed to be estimated and cannot be considered to be absolutely correct.

Autosomal dominant A pathogenic variant in only one gene copy in each cell is sufficient to cause an autosomal dominant disease.


Autosomal recessive Pathogenic variants in both copies of each gene of the chromosome are needed to cause an autosomal recessive disease and observe the mutant phenotype.


dominant X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.


recessive Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder.


Mitochondrial or multigenic Mitochondrial genetic disorders can be caused by changes (mutations) in either the mitochondrial DNA or nuclear DNA that lead to dysfunction of the mitochondria and inadequate production of energy.

Multigenic or multifactor Inheritance involving many factors, of which at least one is genetic but none is of overwhelming importance, as in the causation of a disease by multiple genetic and environmental factors.

Thoracolaryngopelvic dysplasia is a short-rib dysplasia characterized by thoracic dystrophy, laryngeal stenosis and a small pelvis.

Prevalence is unknown but less than 10 cases have been reported in the literature so far.

Clinical description
Patients present with severe respiratory distress (requiring intubation) during the neonatal period. The rib shortening is less severe than in Jeune syndrome (see this term) and the thorax is characteristically small, narrow and bell-shaped. The pelvis is reduced in all dimensions and the combination of the thorax anomalies and the small pelvis give the appearance of a protruding abdomen. Subglottic stenosis has also been described but it remains unclear whether this is a congenital anomaly or is secondary to long-term intubation. In addition, several cases of thoracopelvic dysostosis (without laryngeal involvement) have been described, which could represent heterogeneous expression of the same syndrome or a distinct entity.

Genetic counseling
Transmission is autosomal dominant.

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.
