Investigation of Filaggrin Gene Mutations Among Latinx Patients With Atopic Dermatitis

Description

Filaggrin deficiency is considered a major target for therapy in Atopic Dermatitis (AD).43 The current status quo with regards to FLG LOF mutations as the strongest known genetic risk factor in AD stems from incomplete data as the majority of studies that have previously examined this association have been carried out in only a limited group of populations (i.e., European ancestry).30 Such partial data impedes our full understanding of genetic risk in AD and consequently has implications for disease prognosis and management. The proposed research represents an attempt to examine long-held paradigms in AD as they relate to genetic risk factors and disease. The development of an independent cohort of Latinx subjects with physician-confirmed diagnosis of AD that is also well phenotyped and grouped by ancestry, while also capturing measures of disease severity, will provide the opportunity to examine a population that has been largely absent from prior studies and further advance our understanding of the pathogenomic role FLG LOF variants in AD.
