Disease Profile
Inflammatory linear verrucous epidermal nevus
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.
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.
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
Inflammatory linear verrucous epidermal nevus (ILVEN) is a type of skin overgrowth, called epidermal nevus. It is characterized by skin colored, brown, or reddish, wart-like papules (nevi). The nevi join to form patches or plaques that often follow a pattern on the skin known as the "lines of Blaschko". The affected areas of the skin may be red, itchy, and inflamed. ILVEN typically presents from birth to early childhood and often is limited to one side of the lower half of the body. It affects females more often than males.[1][2][3] It usually occurs alone; however, rarely ILVEN can be associated with other symptoms as part of an epidermal nevus syndrome.[2] Rarely, ILVEN can become cancerous (for example, basal cell carcinoma or squamous cell carcinoma).[4]
ILVEN is caused by a genetic change that occurs after conception (
