Primary immunodeficiency or monogenic inflammatory bowel disease v2.535 ALPI Arina Puzriakova Source Expert Review Green was added to ALPI.
Added phenotypes Intestinal Alkaline Phosphatase deficiency for gene: ALPI
Publications for gene: ALPI were updated from 32086639; 32048120; 29567797 to 32048120; 29567797; 32086639
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Primary immunodeficiency or monogenic inflammatory bowel disease v2.128 ALPI Eleanor Williams Classified gene: ALPI as Amber List (moderate evidence)
Primary immunodeficiency or monogenic inflammatory bowel disease v2.128 ALPI Eleanor Williams Added comment: Comment on list classification: Changing rating from red to amber. 2 cases reported plus some functional data.
Primary immunodeficiency or monogenic inflammatory bowel disease v2.128 ALPI Eleanor Williams Gene: alpi has been classified as Amber List (Moderate Evidence).
Primary immunodeficiency or monogenic inflammatory bowel disease v2.127 ALPI Eleanor Williams changed review comment from: Not associated with a phenotype in OMIM or Gene2Phenotype.

PMID: 29567797 - report ALPI mutations in two unrelated patients with severe intestinal inflammation and autoimmunity. WES was used. Patient 1 - non‐consanguineous parents. At 2 years old was diagnosed with coeliac disease from HLA-typing. At age 3 had recurrent abdominal pain, rectal bleeding and severe diarrhoea. Patient 2 - non‐consanguineous parents of Jewish Ashkenazi origin. Age 15 he was diagnosed with ileocolonic Crohn's disease. Compound heterozygous mutations in the ALPI gene were found in both patients. Three variants result in the substitution of residues highly conserved across species (A97T, A350V and A360) and one variant (Q439X) introducing a premature stop codon. Functional studies in HEK293T cells showed that all ALPI mutations were loss of function. ALPI expression was reduced in patients’ biopsies.; to: Not associated with a phenotype in OMIM or Gene2Phenotype.
