Genes affected

PLVAP (HGNC:13635): (plasmalemma vesicle associated protein) Predicted to enable identical protein binding activity. Involved in MAPK cascade; positive regulation of cellular extravasation; and tumor necrosis factor-mediated signaling pathway. Located in cell surface. Colocalizes with caveola. Implicated in congenital diarrhea. [provided by Alliance of Genome Resources, Apr 2022]

PLVAP Gene-Disease associations (from GenCC):

• diarrhea 10, protein-losing enteropathy type

  Inheritance: AR Classification: STRONG, MODERATE Submitted by: Ambry Genetics, Labcorp Genetics (formerly Invitae)
• congenital diarrhea 7 with exudative enteropathy

  Inheritance: AR Classification: SUPPORTIVE Submitted by: Orphanet
