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]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.44).
• BP6: Variant 3-132328263-T-C is Benign according to our data. Variant chr3-132328263-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 740129.Status of the report is criteria_provided_single_submitter, 1 stars.
