This disorder may be linked to stagnant expression of GATA-4 and Cdx-2 coincident with increased expression of HNF-1,in experiments performed on the CaCo-2 cell line.

Studies from Nigeria show that the Yoruba exhibit high incidences of thiscondition, whereas the Fulani don't suffer from it. People with this disorder do not have a mutation in the MCM6 gene onthe long arm of chromosome 2, thereby displaying a phenotype known as persistence. In infants, this disorder is diagnosed bymeasuring a pH of lower than 5.5 in the stool. Formic acid lyase produces H2 and CO2 from the cleavage of E. coli-producedformic acid in this disorder, providing the basis for its diagnosis with the hydrogen breath test. A workaround for this disorderinvolves ingesting puriÂfied beta-galactosidase. This trait arises when galactose and glucose are not produced by an enzymewhose levels drop dramatically aftfter weaning. For 10 points, name this trait common in Asian populations, whose sufferers areunable to digest the sugar found in milk.
