  In congenital lactase deficiency, a very rare genetic disorder (affecting fewer than 50 patients in the world, mainly in Finland), lactase activity is drastically reduced or non-existent. (1) Infants with this disease can experience symptoms such as nausea [yogurtinnutrition.com]

  One symptom that typically is not seen, however, is loss of appetite. In fact, most infants who have CLD have an exceptionally good appetite and even appear hungry and eager to eat much of the time. [brighthub.com]

Without treatment, they may become dehydrated, lose weight and experience malnutrition. Symptoms usually start during the first week of life when an infant is given breast milk or formula (which will contain lactose) for the first time. [thinkgenetic.com]

The onset of symptoms typically occurs in early infancy and the course and prognosis vary depending on the underlying cause. 1 Congenital lactose deficiency is caused by very low levels or the absence of lactase-phlorizin hydrolase (commonly known as [analesdepediatria.org]

Pathophysiology The lactase enzyme is located in the brush border (microvilli) of the small intestine enterocyte. The enzyme splits and hydrolyzes dietary lactose into glucose and galactose for transport across the cell membrane. [aafp.org]

Secondary Lactase Deficiency Secondary lactase deficiency implies that an underlying pathophysiologic condition is responsible for the lactase deficiency and subsequent lactose malabsorption. [pediatrics.aappublications.org]

Its deficiency prevents the hydrolysis of lactose and causes osmotic diarrhoea when the child starts breastfeeding. 2,3 At first it was believed that CLD was a severe form of lactose intolerance with early onset. 4 But while both disorders are due to [analesdepediatria.org]

Prevention In only one of the three types of lactose intolerance can this disorder be prevented. This can be done by preventing the mentioned diseases, some of which are also congenital. [tellmegen.com]

Congenital lactase deficiency Congenital lactase deficiency is a very rare, autosomal recessive genetic disorder that prevents lactase expression from the first feed.  Congenital lactose intolerance is serioue disorder in which the infants may fail to [slideshare.net]

Thus, diseases that markedly speed up transit of lactose through the small intestine prevent lactose from being fully digested and absorbed, leading to a misdiagnosis of lactose intolerance. [rxlist.com]
