Immunodeficiency-70 (IMD70) is an autosomal dominant immunologic disorder characterized by severe cutaneous warts on the hands, feet, and face, suggesting increased susceptibility to human papillomavirus (HPV) infection. Affected individuals may also have recurrent bacterial infections, such as sinusitis, as well as feature of autoinflammation, such as colitis, celiac disease, and retinal vasculitis. Laboratory studies show decreased CD4+ T cells and decreased CD19+ B cells; hypogammaglobulinemia has also been observed (summary by Thaventhiran et al., 2020). [from OMIM]

Immunodeficiency-79 (IMD79) is an autosomal recessive disorder characterized by childhood onset of recurrent and recalcitrant skin warts due to uncontrolled viral infection with human papillomavirus (HPV). Some patients may also have recurrent respiratory infections beginning in childhood, but the phenotype overall is mild compared to other primary immunodeficiencies. Patients may not come to attention until adulthood. Laboratory studies show absence of the CD4 antigen on T cells, monocytes, and dendritic cells, with variable secondary abnormalities in B cells and NK cells due to lack of CD4+ T cells (summary by Lisco et al., 2021). [from OMIM]
