Thundering hoofbeats and dazzling zebras: A model integrating current rare disease perspectives in paleopathology.

Objective: The article reviews the study of rare diseases and their nomenclature, emerging government policies and initiatives, and the concerns voiced by the modern rare disease communities. An interpretive model is then presented for the bioarchaeological interpretations of individuals with paleopathological evidence of rare diseases.

Materials: In demonstration of the application of the proposed framework, we evaluate the skeletal remains of an adult female (EZ 3-7-1) excavated in the 1980s from the Middle Woodland (50BCE-CE400) context of the Elizabeth site (11PK512) in the lower Illinois Valley, USA.

Overlapping genetic pathways in the skeletal dysplasias of a middle woodland individual: A case study.

Studies of interacting/overlapping genetic skeletal disorders are rare for populations today, but even more so for archaeological contexts. The skeletal remains of an adult female (EZ 3-7-1) were excavated in the 1980s from the Middle Woodland (50BC-AD400) context of the Elizabeth site (11PK512) in the lower Illinois Valley (LIV), USA. Reported here are the standard score (z-score) comparisons of the measured skeletal differences of EZ 3-7-1 with a reference sample and a re-analysis of the individual's pathological changes, with special consideration placed on refining the disease diagnosis.
