Este novo tipo de diarreia congênita malabsortiva é caracterizado por má absorção generalizada e escassez de células enteroendócrinas. Os pacientes se apresentam durante as primeiras semanas de vida com vômitos, diarreia, desidratação e acidose metabólica hiperclorêmica grave após a ingestão de fórmula padrão à base de leite de vaca. Também foi associado a diabetes tipo 1 durante a infância. Este fenótipo é causado por mutações de perda de função no gene NEUROG3, que codifica a neurogenina 3, uma proteína implicada no desenvolvimento de células endócrinas entéricas e pancreáticas. | |||
