Maret co-published an article that provides guidance and background to physicians on how to treat patients with rare genetic disorders causing extremely low cholesterol and triglycerides in their blood. The disorder causes an inability to absorb vitamin E and properly transport it to tissues in the body.

This article has personal significance to Maret, as she once helped a patient whose brother had died of vitamin E deficiency. This patient was treated with grams of vitamin E per day, and by helping her figure out what to eat to avoid various nutritional deficiencies she was healthy enough to have two children and now is a grandmother. Around 40 years later, this patient still keeps in touch with Maret.
