Genes affected
ALPG (HGNC:441): (alkaline phosphatase, germ cell) There are at least four distinct but related alkaline phosphatases: intestinal, placental, placental-like, and liver/bone/kidney (tissue non-specific). The product of this gene is a membrane bound glycosylated enzyme, localized to testis, thymus and certain germ cell tumors, that is closely related to both the placental and intestinal forms of alkaline phosphatase.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 30, 2024The c.124G>A (p.A42T) alteration is located in exon 2 (coding exon 2) of the ALPPL2 gene. This alteration results from a G to A substitution at nucleotide position 124, causing the alanine (A) at amino acid position 42 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
