Not associated with a phenotype in OMIM or Gene2Phenotype.

PMID: 29567797 - Parlato et al 2018- 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.
