In this presentation, I would like to show some of the countless contributions and relevance of kinship today. To this end, my focus will be on kinship studies dialog with other areas of anthropology - such as medical anthropology -, with interdisciplinary issues triggered by new technologies. To this end, I will bring together kinship studies and new kinship studies to think about the mutual contributions that both currents - as well as family studies - can make to the advancement of interdisciplinary research. In order to do this, I intend to start with my current research about a hereditary syndrome that I have been studying in Brazil and which predisposes to cancer. The current fieldwork on a subject from the field of medical anthropology has given me new thoughts on kinship studies. One of the points is the notion of transmission and heredity in a country where family configurations can be quite diverse. In addition, this research has raised questions about the interactions of genetics and kinship configurations. To cover these issues and debates, in addition to my research, I also intend to return to and dialog with authors from medical and health anthropology and (new) kinship studies who have made these connections, such as Gibbon (2021), Fonseca (2015) and Finkler (2021), among others
