Ancient DNA analysis of rare genetic bone disorders

Abstract

ObjectiveReview of the current advancements in the field of paleogenetics that provide new opportunities in studying the evolution of rare genetic bone diseases. Material and MethodsBased on cases from the literature, the genetics of rare bone diseases will be introduced and the main methodological issues will be addressed, focusing on the opportunities presented by the application of aDNA analyses in the field of paleopathology. ResultsMedical literature provides large datasets on the genes responsible for rare bone disorders. These genes, subdivided in functional categories, display important future targets when analyzing rare genetic bone disorders in ancient human remains. ConclusionsKnowledge on both phenotype and genotype is required to study rare diseases in ancient human remains. SignificanceThe proposed interdisciplinary research will provide new insight into the occurrence and spread of genetic risk factors in the past and will help in the diagnostics of these rare and often neglected diseases. LimitationsThe current limitations in ancient DNA research and targeting the disease-causing specific mutations (e.g., somatic or germline). Suggestions for Further ResearchMethodological advancements and candidate gene lists provide the optimal basis for future interdisciplinary studies of rare genetic bone disorders in ancient human remains.
