Immunological abnormalities in patients with early-onset ataxia with ocular motor apraxia and hypoalbuminemia

In this study, we report that EAOH patients have immunological abnormalities, including lymphopenia; decreased levels of CD4+ T-cells, CD8+ T-cells, and B-cells; hypogammaglobulinemia; low T-cell recombination excision circles and kappa-deleting element recombination circles; and oligoclonality of T-cell receptor β-chain variable repertoire. These immunological abnormalities vary among the EAOH patients. Additionally, mild radiosensitivity in the lymphocytes obtained from the patients with EAOH was demonstrated. These findings suggested that the immunological abnormalities and mild radiosensitivity evident in patients with EAOH could be probably caused by the DNA repair defects.PMID:34118401 | DOI:10.1016/j.clim.2021.108776
