The coroner is a “clear, dome-like covering over the front of the eye”, and a white or grey arc may develop around the coloured part of the eye (known as the iris), when cholesterol levels are high.

People who have inherited the genetic mutation leading to extremely high cholesterol will usually have a high cholesterol reading.
A cholesterol reading, which can be detected via a blood test, will show a reading of LDL cholesterol above 11mmol/L for children under the age of 18.
