Systemic lupus erythematosus-17 (SLEB17) is an X-linked dominant autoimmune disorder characterized by onset of systemic autoinflammatory symptoms in the first decades of life. Only affected females have been reported. Features may include classic features of SLE, such as malar rash and arthralgias, or can include less common entities such as hemiplegia and neuromyelitis optica (NMO). Laboratory studies show the presence of autoantibodies and enhanced NFKB (164011) signaling, the latter being consistent with a gain-of-function effect (Brown et al., 2022). For a phenotypic description and a discussion of genetic heterogeneity of systemic lupus erythematosus (SLE), see 152700. [from OMIM]

Immunodeficiency-82 with systemic inflammation (IMD82) is a complex autosomal dominant immunologic disorder characterized by recurrent infections with various organisms, as well as noninfectious inflammation manifest as lymphocytic organ infiltration with gastritis, colitis, and lung, liver, CNS, or skin disease. One of the more common features is inflammation of the stomach and bowel. Most patients develop symptoms in infancy or early childhood; the severity is variable. There may be accompanying fever, elevated white blood cell count, decreased B cells, hypogammaglobulinemia, increased C-reactive protein (CRP; 123260), and a generalized hyperinflammatory state. Immunologic workup shows variable B- and T-cell abnormalities such as skewed subgroups. Patients have a propensity for the development of lymphoma, usually in adulthood. At the molecular level, the disorder results from a gain-of-function mutation that leads to constitutive and enhanced activation of the intracellular inflammatory signaling pathway. Treatment with SYK inhibitors rescued human cell abnormalities and resulted in clinical improvement in mice (Wang et al., 2021). [from OMIM]

Sjogren syndrome is an autoimmune disease that mainly affects the exocrine glands. It is clinically characterized by keratoconjunctivitis sicca and xerostomia (Goransson et al., 2006). See 200400 for association of Sjogren syndrome with achalasia in sisters. [from OMIM]

An autoimmune, connective tissue chronic inflammatory disorder affecting the skin, joints, kidneys, lungs, heart, and the peripheral blood cells. It is more commonly seen in women than men. Variants include discoid and systemic lupus erythematosus. [from NCI]

A common form of systemic amyloidosis characterized by deposition of wild type transthyretin predominantly in the heart and the soft tissues (mainly the carpal tunnel region, lumbar canal and tendons). [from ORDO]

Systemic lupus erythematosus (SLE) is a complex autoimmune disease characterized by production of autoantibodies against nuclear, cytoplasmic, and cell surface molecules that transcend organ-specific boundaries. Tissue deposition of antibodies or immune complexes induces inflammation and subsequent injury of multiple organs and finally results in clinical manifestations of SLE, including glomerulonephritis, dermatitis, thrombosis, vasculitis, seizures, and arthritis. Evidence strongly suggests the involvement of genetic components in SLE susceptibility (summary by Oishi et al., 2008). Genetic Heterogeneity of Systemic Lupus Erythematosus An autosomal recessive form of systemic lupus erythematosus (SLEB16; 614420) is caused by mutation in the DNASE1L3 gene (602244) on chromosome 3p14.3. An X-linked dominant form of SLE (SLEB17; 301080) is caused by heterozygous mutation in the TLR7 gene (300365) on chromosome Xp22. See MAPPING and MOLECULAR GENETICS sections for a discussion of genetic heterogeneity of susceptibility to SLE. [from OMIM]
