Vulvar cancer

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

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

Vulvar cancer is the abnormal growth of cells of the vulva, which is part of the female reproductive system and includes the vaginal lips, clitoris, and part of the vagina. Symptoms of vulvar cancer may consist of a lump (mass), itching, or unusual bleeding. Though the exact cause of this cancer is unknown, older women and those who have human papillomavirus have a higher chance of developing vulvar cancer. Treatment may include laser therapy, surgery, chemotherapy, or radiation therapy.[1]

Cause

Most vulvar cancers occur by chance due to older age or human papillomavirus infection. However, an inherited condition called Fanconi anemia is associated with a significantly increased risk for vulvar cancer.[2] This condition is very rare and may cause only a small proportion of all vulvar cancers. There is also some evidence that a small number of vulvar cancers may be related to a genetic predisposition: one research study found that relatives of individuals with vulvar cancer have a slightly increased risk to develop vulvar cancer, which suggests there may be a genetic component to this disease that could be shared by family members, but the specific gene is not yet known.[3]

Organizations

Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer. Inclusion on this list is not an endorsement by GARD.
