X-linked lymphoproliferative disease due to XIAP deficiency

X-linked lymphoproliferative disease (XLP) has two recognizable subtypes, XLP1 and XLP2. XLP1 is characterized predominantly by one of three commonly recognized phenotypes: Inappropriate immune response to Epstein-Barr virus (EBV) infection leading to hemophagocytic lymphohistiocytosis (HLH) or severe mononucleosis. Dysgammaglobulinemia. Lymphoproliferative disease (malignant lymphoma). XLP2 is most often characterized by HLH (often associated with EBV), dysgammaglobulinemia, and inflammatory bowel disease. HLH resulting from EBV infection is associated with an unregulated and exaggerated immune response with widespread proliferation of cytotoxic T cells, EBV-infected B cells, and macrophages. Dysgammaglobulinemia is typically hypogammaglobulinemia of one or more immunoglobulin subclasses. The malignant lymphomas are typically B-cell lymphomas, non-Hodgkin type, often extranodal, and in particular involving the intestine. [from GeneReviews]

Pachyonychia congenita 2

Pachyonychia congenita (PC) is characterized by hypertrophic nail dystrophy, painful palmoplantar keratoderma and blistering, oral leukokeratosis, pilosebaceous cysts (including steatocystoma and vellus hair cysts), palmoplantar hyperhydrosis, and follicular keratoses on the trunk and extremities. [from GeneReviews]

Keratosis follicularis spinulosa decalvans, X-linked

Keratosis follicularis spinulosa decalvans is an uncommon genodermatosis chiefly characterized by widespread keratosis pilaris, progressive cicatricial alopecia of the scalp, eyebrows, and eyelashes, and an excess of affected males. Photophobia, blepharitis/conjunctivitis, and corneal dystrophy are characteristic ancillary findings. It is most often inherited as an X-linked trait (summary by Castori et al., 2009). Autosomal dominant inheritance has also been reported (KFSD; 612843). The term 'cum ophiasi' means 'with ophiasis,' i.e., baldness in 1 or more winding streaks about the head, which comes from the Greek for snake. Decalvans refers to the loss of hair. [from OMIM]

Immunodeficiency 51

Immunodeficiency-51 (IMD51) is an autosomal recessive primary immune deficiency that is usually characterized by onset of chronic mucocutaneous candidiasis in the first years of life. Most patients also show recurrent Staphylococcal skin infections, and may show increased susceptibility to chronic bacterial respiratory infections. Patient cells show a lack of cellular responses to stimulation with certain IL17 isoforms, including IL17A (603149), IL17F (606496), IL17A/F, and IL17E (IL25; 605658) (summary by Levy et al., 2016). [from OMIM]

Keratosis follicularis spinulosa decalvans, autosomal dominant

Keratosis follicularis spinulosa decalvans (KFSD) is an uncommon genodermatosis characterized by follicular hyperkeratosis, progressive cicatricial alopecia, and photophobia. Most reported cases show X-linked inheritance (KFSDX; 308800) (Castori et al., 2009). [from OMIM]
