Genes affected
ALPI (HGNC:437): (alkaline phosphatase, intestinal) There are at least four distinct but related alkaline phosphatases: intestinal, placental, placental-like, and liver/bone/kidney (tissue non-specific). The intestinal alkaline phosphatase gene encodes a digestive brush-border enzyme. This enzyme is a component of the gut mucosal defense system and is thought to function in the detoxification of lipopolysaccharide, and in the prevention of bacterial translocation in the gut.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 06, 2021The c.371C>T (p.A124V) alteration is located in exon 4 (coding exon 4) of the ALPI gene. This alteration results from a C to T substitution at nucleotide position 371, causing the alanine (A) at amino acid position 124 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
