Genetic Variant ACP4:p.Thr143Arg (chr19-50791780-C-G) – ACMG Classification: Uncertain_significance (5 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 5 ACMG points: 6P and 1B. PM5PP3_StrongBS2_Supporting

The NM_033068.3(ACP4):c.428C>G(p.Thr143Arg) variant causes a missense change. The variant allele was found at a frequency of 0.00000559 in 1,610,330 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T143M) has been classified as Pathogenic.

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 5 ACMG points.

PM5

Other missense variant is known to change same aminoacid residue: Variant chr19-50791780-C-T is described in ClinVar as Pathogenic. ClinVar VariationId is 375700.Status of the report is no_assertion_criteria_provided, 0 stars.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.959

BS2

High AC in GnomAdExome4 at 8 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
