Summaries for Dowling-Degos Disease 2

OMIM : 53 Dowling-Degos disease (DDD) is an autosomal dominant genodermatosis characterized by reticular pigmentation, usually in a flexural distribution. However, generalized DDD can also occur, with numerous hypopigmented or erythematous macules and papules on the neck, chest, and abdomen. The histopathology of DDD shows characteristic thin branch-like patterns of epidermal downgrowth (summary by Li et al., 2013). (615327)

MalaCards based summary : Dowling-Degos Disease 2, is also known as ddd2, and has symptoms including follicular hyperkeratosis, reticular hyperpigmentation and hypomelanotic macule. An important gene associated with Dowling-Degos Disease 2 is POFUT1 (Protein O-Fucosyltransferase 1). Affiliated tissues include skin.

UniProtKB/Swiss-Prot : 71 Dowling-Degos disease 2: An autosomal dominant genodermatosis. Affected individuals develop a postpubertal reticulate hyperpigmentation that is progressive and disfiguring, and small hyperkeratotic dark brown papules that affect mainly the flexures and great skin folds. Patients usually show no abnormalities of the hair or nails.
