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.

Inheritance

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.

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.

Summary

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

Orpha Number: 2634

Definition
A rare disorder characterized by disproportionate short stature from birth with dysplasia of the ulna and fibula.

Epidemiology
Prevalence is unknown but only a few families have been described in the literature so far.

Clinical description
Curvatures of the forearm, radial head luxation, and tibial anomalies have also been described.

Etiology
The syndrome is transmitted in an autosomal dominant manner and cases of this dysplasia have been described in families with Langer mesomelic dwarfism and Léri-Weill dyschondrosteosis (see these terms) leading to the suggestion that this dysplasia, type Reinhardt-Pfeiffer may also be associated with haploinsufficiency of the short stature homeobox (SHOX; Xp22.33 and Yp11.32) gene or anomalies of the downstream pseudoautosomal region 1 (PAR1) where SHOX enhancer elements are located.

Symptoms

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.
