Dirofilariasis

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

no.svg

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

no.svg

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

no.svg

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.

no.svg

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

Dirofilariasis refers to infections caused by Dirofilaria roundworms. Although the natural hosts of these roundworms are dogs, wild canids (such as wolves and foxes) and raccoons, humans can be infected with Dirofilaria larvae through mosquito bites. Signs and symptoms of dirofilariasis generally include nodules under the skin or lung granulomas (small nodules formed by an inflammatory reaction) which may be asymptomatic. Some people with dirofilariasis of the lungs may also experience cough, chest pain, fever, wheezing, chills, and pleural effusion (excess fluid between the tissues that line the lungs and the chest cavity). Dirofilariasis is treated with surgical removal of lung granulomas and skin nodules.[1][2]
