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.

Mar 14, 2023

The c.154G>A (p.A52T) 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 154, causing the alanine (A) at amino acid position 52 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
