Chronic mucocutaneous candidiasis (CMC) includes a group of rare disorders with altered immune responses, selective against Candida, characterized by persistent and/or recurrent infections of the skin, nails, and mucous membranes, caused by organisms of the genus Candida, mainly Candida albicans (Zuccarello et al., 2002).
Isolated familial chronic mucocutaneous candidiasis is distinct from candidiasis with endocrinopathy (240300).
In myeloperoxidase deficiency (254600), susceptibility to candidiasis may be increased.
Genetic Heterogeneity of Candidiasis
Familial candidiasis-1 (CANDF1) maps to chromosome 2p. CANDF2 (212050) is caused by mutation in the CARD9 gene (607212) on chromosome 9q34.3. CANDF3 (607644), a form restricted to nails of the hands and feet, maps to chromosome 11. CANDF4 (613108) is caused by mutation in the CLEC7A gene (606264) on chromosome 12p13. CANDF6 (613956) is caused by mutation in the IL17F gene (606496) on chromosome 6p12. CANDF7 (614162) is caused by mutation in the STAT1 gene (600555) on chromosome 2q32. CANDF8 (615527) is caused by mutation in the TRAF3IP2 gene (607043) on chromosome 6q21. CANDF9 (616445) is caused by mutation in the IL17RC gene (610925) on chromosome 3p25.
A form of familial candidiasis, previously thought to be isolated and designated CANDF5, has been found to be part of a primary immune deficiency (IMD51; 613953) that includes Staphylococcal skin infections and increased susceptibility to chronic bacterial respiratory infections. [from
