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]

Oct 28, 2016

Leeds Amelogenesis Imperfecta Research Group, University of Leeds

Significance: Pathogenic

Review Status: no assertion criteria provided

Collection Method: research

The variant was identified in ExAC in 9 out of 89042 alleles (always in a heterozygous state) and has been assigned rs546603773 with 0.02% MAF in dbSNP146. The variant is predicted to be damaging by multiple pathogenicity prediciton softwares including Polyphen-2, SIFT, CADD. The residue predicted to be affected is conserved in paralogues and mammalian orthologues in all species analysed, except for horse in which the region surrounding the residue is not present. The residue is in the extracellular domain (residues 29-390) of ACPT. The substitution of threonine at residue 143 for methionine (NP_149059.1) will alter the residue from a small polar to a larger nonpolar one (BLOSUM62 score -1). -
