Disease Profile


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.


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.

Inhalation of barytes; Deposition of barium in the lungs


Baritosis is an extremely rare, benign form of pneumoconiosis that causes little or no overgrowth, hardening, and/or scarring of the tissue in the lung (fibrosis). Pneumoconiosis is caused by accumulation of inhaled particles and involves a reaction of tissue in the lung.[1] In the case of baritosis, the inhaled particles are made up of barium sulfate and is well described in workers who crush and grind compounds containing barium, a mineral found in paints, paper, ceramics, glass, rubber, electronic components, and in drilling muds in oil and gas exploration.[1] [2] Baritosis is typically characterized by a mixture of very fine punctate and annular (ring-like) lesions and some slightly larger nodular lesions in the lung. The condition generally appears 1 to 2 years after exposure, does not affect the function of the lung, and appears to go away without treatment after exposure stops.[2]
