Gene name Maltase-glucoamylase, intestinal
Gene symbol MGAM
Organism Homo sapiens
NCBI taxa ID 9606
Cleft type
Developmental stage
Data sources Manually collected
Reference 25776870
Functional description May serve as an alternate pathway for starch digestion when luminal alpha-amylase activity is reduced because of immaturity or malnutrition. May play a unique role in the digestion of malted dietary oligosaccharides used in food manufacturing.
