Olmsted syndrome is characterized by symmetrically distributed, destructive, inflammatory palmoplantar keratoderma with periorificial keratotic plaques, most commonly due to gain-of-function mutations in the transient receptor potential vanilloid 3 (TRPV3) gene, which involves multiple pathological functions of the skin, such as hyperkeratosis, dermatitis, hair loss, itching, and pain. Recent studies suggest that mutations of located in different structural domains lead to cases of varying severity, suggesting a potential genotype-phenotype correlation resulting from TRPV3 gene mutations. This paper reviews the genetics and pathogenesis of Olmsted syndrome, as well as the potential management and treatment.

Aims: Define the relationship between N-terminal atrial natriuretic peptide (NT-ANP) levels and incident metabolic syndrome and type 2 diabetes mellitus ('metabolic disease') in healthy adults and develop a risk prediction score.

Materials And Methods: Retrospective cohort study of Olmsted County Heart Function Study participants, a random sampling of county residents aged 45 years and older (n = 2042). Clinical data were collected during enrolment between 1997 and 2000 and upon follow-up 4 years later.

Background: Olmsted syndrome (OS) is a rare genodermatosis predominantly inherited in an autosomal dominant manner, typically arising from gain-of-function (GOF) variants in the transient receptor potential channel vanilloid 3 (TRPV3) gene.

Objective: This study aims to investigate potential mechanisms underlying OS in two cases presenting with an autosomal recessive inheritance pattern.

Methods: Next-generation sequencing panel was employed to identify TRPV3 variants.
