Genes affected

ACP5 (HGNC:124): (acid phosphatase 5, tartrate resistant) This gene encodes an iron containing glycoprotein which catalyzes the conversion of orthophosphoric monoester to alcohol and orthophosphate. It is the most basic of the acid phosphatases and is the only form not inhibited by L(+)-tartrate. [provided by RefSeq, Aug 2008]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.019371897).

BS1

Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.0000591 (9/152290) while in subpopulation EAS AF= 0.000966 (5/5174). AF 95% confidence interval is 0.00038. There are 0 homozygotes in gnomad4. There are 8 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 46 of the ACP5 protein (p.Arg46Gln). This variant is present in population databases (rs201184983, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with ACP5-related conditions. ClinVar contains an entry for this variant (Variation ID: 464886). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
