Vohwinkel syndrome

Vohwinkel syndrome, also known as keratoderma hereditaria mutilans, is a rare autosomal dominant skin disorder that primarily affects the epidermal differentiation and stratum corneum.1 It is caused by genetic changes in the LORICRIN gene.2

Patients with Vohwinkel syndrome typically present with dry, thickened, and scaly skin on the palms and soles, which can lead to painful fissures and calluses. Additionally, they may experience hearing loss due to deformities in the outer ear and recurrent infections. Nail abnormalities, such as thickened nails and pterygium formation, have also been observed in some individuals with this syndrome.1

Diagnosing Vohwinkel syndrome involves clinical evaluation, genetic testing, and additional tests to assess the extent of skin and hearing abnormalities. Genetic testing can confirm the presence of a variant in the LORICRIN gene. Genetic counselors can provide more information on the testing process and available resources.2

Patients with Vohwinkel syndrome can find support and information from various resources, such as the Online Mendelian Inheritance in Man (OMIM) database, the Human Gene Mutation Database (HGMD), and the Genetic and Rare Diseases Information Center (GARD). These resources contain detailed information on the condition, associated genes, and available clinical trials.3

Management of Vohwinkel syndrome typically involves symptomatic treatment, such as regular moisturization of the skin and use of keratolytic agents to reduce scaling. Regular follow-up with a dermatologist and otolaryngologist is recommended to monitor and manage skin and ear-related symptoms. Genetic counseling is also essential for affected individuals and their families to understand inheritance patterns and potential risks.2
