Did Edgar Degas have Stargardt disease?

Area of Science:

• Ophthalmology
• Medical Genetics

Background:

• Investigated the potential hereditary retinal pathology in painter Edgar Degas and his cousin Estelle Musson.
• Explored the possibility of Stargardt disease in Degas due to shared symptoms with Estelle.

Discussion:

• Genetic analysis of Estelle's great-grandchildren (Degas's great-grandnieces) was conducted.
• Searched for mutations in the ABCA4 gene, a known cause of Stargardt disease.

Key Insights:

• No disease-causing ABCA4 gene variations were found in the tested descendants.
• This finding suggests Edgar Degas likely did not have Stargardt disease.

Outlook:

• The shared retinal pathology between Degas and Estelle may be a different hereditary disease.
• Further research is needed to identify the exact cause of their vision loss.
