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]
SMIM47 (HGNC:53452): (small integral membrane protein 47)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 31, 2024The c.424C>T (p.H142Y) alteration is located in exon 4 (coding exon 4) of the ACPT gene. This alteration results from a C to T substitution at nucleotide position 424, causing the histidine (H) at amino acid position 142 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
