This gene is associated with a relevant phenotype in OMIM but not Gene2Phenotype. It is currently Amber with a recommendation to promote to Green on the Intestinal failure panel (Version 1.36) with the following reviews:
"Diarrhoea-10 is a protein-losing enteropathy characterized by intractable secretory diarrhoea and massive protein loss due to leaky fenestrated capillaries. Features include early-onset anasarca, severe hypoalbuminemia, hypogammaglobulinemia, and hypertriglyceridemia, as well as electrolyte abnormalities. Some patients exhibit facial dysmorphism and cardiac and renal anomalies. Intrafamilial variability has been observed, and the disease can be severe, with death occurring in infancy in some patients. Four unrelated families reported. Sources: Expert Review

"Comment on publications: PMID: 26207260. Patient is of Afgan descent born to consanguineous parents. Presented at 8 days of life with secretory diarrhea, metabolic acidosis, lethargy, poor feeding, and severe hyponatremia causing seizures. Further examination shows patient had bilateral colobomas, undescended testes, mildly dysplastic kidneys bilaterally, low-set ears, and micrognathia. PMID: 29875123. 2 patients (first cousins) from a Muslim Arab consanguineous kindred presented with anasarca, severe hypoalbuminaemia and hypogammaglobinaemia. PMID: 29661969. Patient is of Turkish descent born to consanguineous parents. Presented with severe haematochezia and moderate anasarca. Other findings: dysmorphism, metabolic acidosis, electrolyte deficiencies, elevated GGT, choroid plexus cysts, iris cysts, ASD, VSD, dilated megaureter with dilated renal pelvis, venous thrombosis. PMID: 31215290. Patient born to consanguineous parents. As well as intestinal phenotypes, she also had dysmorphic features, renal and cardiac phenotypes.

After discussion with the Geomics England Clinical Team it was decided that this gene should also be on this panel.
