Rheumatoid-like hand deformities and aortic valve disease in a 13-year-old girl with homozygous familial hypercholesterolemia: a case report

This case underscores the significance of identifying important physical signs in the diagnosis and management of familial hypercholesterolemia, particularly in settings where genetic testing may be limited. Moreover, the unique coexistence of familial hypercholesterolemia with hand joint deformity and aortic valvular heart disease serves as a clinical clue that can facilitate diagnosis and appropriate therapeutic interventions. A high index of suspicion is essential for timely diagnosis and tailored management, thus reducing the burden of atherosclerotic heart disease in affected individuals.
