Legendary actress Catherine O'Hara has died at the age of 71 after a brief illness. O'Hara, known for her roles in Home Alone and Schitt's Creek, had a rare genetic condition called situs inversus, which caused her organs to be positioned in a mirror image of normal human anatomy. While the condition is typically harmless, it can sometimes be linked to congenital heart defects. O'Hara first revealed her diagnosis more than 20 years ago during a routine doctor's visit. There is no evidence to suggest situs inversus contributed to her death.

Why it matters
