MYO5B and microvillus inclusion disease: This is in agreement with the notion that preterm birth and birthweight in MVID appeared to be associated with MYO5B mutations, rather than with bowel dysfunctions as such [6], whereas our results suggest that the occurrence of suspected fetal bowel abnormalities in MVID was directly related to bowel disease rather than to variants in specific MVID-associated genes (i.e., MYO5B, STX3, or STXBP2).
