    An unusual combination of common variable immunodeficiency (CVID) and Turner's syndrome in a Saudi woman aged 20 years is presented. In addition to panhypogammaglobulinaemia, the patient had CD4+ T lymphocytopenia; however, there was evidence of in vivo activation of T cells and overproduction of soluble interleukin 2 receptor in culture supernate. Mantoux test was positive, but lymphoblastic response to non-specific mitogen was impaired. Immunogenetically the patient was HLA-DR3 positive and karyotypically she was a mosaic (45XO/46XX) with ring X chromosome (46Xr(X)). The presence of severe kyphoscoliosis was possibly related to ring X chromosome. This case highlights the grave consequences of the delayed diagnosis of immunodeficiency and emphasises the heterogeneous nature of CVID.
