Meeting report: AT workshop 2023-A platform for discussing cutting-edge science in DNA damage signaling, repair, and human disorders.

Ataxia-telangiectasia (A-T) is a rare devastating hereditary condition, which affects multiple organ systems including cerebellar motor function as well as DNA repair, resulting in a higher incidence of cancer and immunodeficiency. The genetic defect in A-T lies in ATM kinase, which is activated by DNA damage and regulates a plethora of substrates including the p53 tumor suppressor. We have organized an international meeting "The 19th Ataxia-Telangiectasia Workshop 2023 (ATW2023)" with support from the Molecular Biology Society of Japan (MBSJ) and other funders. Here, we report that ATW2023 was successfully held in Kyoto from March 2nd to 5th, 2023 with more than 150 participants traveling from all over the world, despite the still smoldering COVID-19 pandemic. In this meeting report, we will briefly describe the highlights of the meeting and would like to express our gratitude to the MBSJ for the financial support.
