Acropectorovertebral dysplasia F form

Prevalence ?
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.

Age of Onset





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


X-linked 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.


X-linked 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.

The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.

Orpha Number: 957

A rare skeletal dysplasia characterized by fusion of the carpal and tarsal bones, with complex anomalies of the fingers and toes (preaxial polydactyly of the hands and/or feet, syndactyly of fingers and toes, hypoplasia and dysgenesis of metatarsal bones).

It has been described in less than 30 patients from three unrelated families.

Clinical description
Other manifestations include prominence of the sternum with variable pectus excavatum, lumbosacral spina bifida occulta, minor craniofacial anomalies and mild intellectual deficit.

The causative gene has been mapped to chromosome region 2q36.

Genetic counseling
This syndrome is transmitted as an autosomal dominant trait with full penetrance.

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.
