Genes affected

ACP4 (HGNC:14376): (acid phosphatase 4) Acid phosphatases are enzymes capable of hydrolyzing orthophosphoric acid esters in an acid medium. This gene is up-regulated by androgens and is down-regulated by estrogens in the prostate cancer cell line. This gene exhibits a lower level of expression in testicular cancer tissues than in normal tissues. The protein encoded by this gene has structural similarity to prostatic and lysosomal acid phosphatases. Alternatively spliced transcript variants have been described, but their biological validity has not been determined. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 3 ACMG points.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.985

BS2

High AC in GnomAdExome4 at 12 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

The c.364G>A (p.G122R) alteration is located in exon 4 (coding exon 4) of the ACPT gene. This alteration results from a G to A substitution at nucleotide position 364, causing the glycine (G) at amino acid position 122 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
