Genes affected

ACP3 (HGNC:125): (acid phosphatase 3) This gene encodes an enzyme that catalyzes the conversion of orthophosphoric monoester to alcohol and orthophosphate. It is synthesized under androgen regulation and is secreted by the epithelial cells of the prostate gland. An alternatively spliced transcript variant encoding a longer isoform has been found for this gene. This isoform contains a transmembrane domain and is localized in the plasma membrane-endosomal-lysosomal pathway. [provided by RefSeq, Sep 2008]

The c.382G>T (p.G128C) alteration is located in exon 4 (coding exon 4) of the ACPP gene. This alteration results from a G to T substitution at nucleotide position 382, causing the glycine (G) at amino acid position 128 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
