Chronic periodontitis, formerly called adult periodontitis, is the most frequently occurring form of periodontitis and is characterized by slowly progressing alveolar bone destruction and attachment loss. Although chronic periodontitis is most prevalent in adults and has a slow progression, it can occur in children and adolescents and may have periods of rapid progression (Armitage, 1999). [from OMIM]

Common variable immunodeficiency-10 (CVID10) is an autosomal dominant primary immunodeficiency characterized by childhood-onset of recurrent infections, hypogammaglobulinemia, and decreased numbers of memory and marginal zone B cells. Some patients may develop autoimmune features and have circulating autoantibodies. An unusual feature is central adrenal insufficiency (summary by Chen et al., 2013). For a general description and a discussion of genetic heterogeneity of common variable immunodeficiency, see CVID1 (607594). [from OMIM]
