TMEM232 (transmembrane protein 232) is a transmembrane protein located on chromosome 5.1 with established roles in immune regulation and skin inflammation. Primary function: TMEM232 promotes inflammatory responses in atopic dermatitis (AD) by activating nuclear factor-κB and STAT3 signaling pathways 1. The protein is regulated by the interleukin-4/STAT6 axis, which forms a self-amplifying inflammatory loop 1. Disease relevance: TMEM232 expression is significantly upregulated in AD skin lesions and in keratinocytes stimulated with inflammatory factors 1. Multiple genetic association studies confirm TMEM232 as a susceptibility gene for AD across diverse populations, with specific variants (rs11357450, rs17132261) showing strong associations 2345. TMEM232 variants interact with other AD susceptibility loci (PRKAG2, TNFRSF6B-ZGPAT) to confer disease risk 6. Interestingly, TMEM232 has also been identified in rare biallelic variants associated with autism spectrum disorder in consanguineous populations 7. Clinical significance: TMEM232 represents a potential therapeutic target, as topical application of TMEM232-targeting siRNA markedly ameliorated AD-like lesions in mouse models 1. The gene's contribution to AD risk is modulated by maternal allergic history and sensitization status 5.
