A young patient is diagnosed with the genetic disorder lactose intolerance, which results in the inability to digest milk products due to a missing enzyme called lactase. What is most likely the cause of lactose intolerance in this patient?

Lactose intolerance is caused when your body has a deficiency of an intestinal enzyme that splits lactose into other forms like glucose, glucose, or sugars that allows this to be absorbed by the intestine. The most likely reason for this condition is that it was inherited from a family member with the same genetic disorder.
