Genes affected

ACP1 (HGNC:122): (acid phosphatase 1) The product of this gene belongs to the phosphotyrosine protein phosphatase family of proteins. It functions as an acid phosphatase and a protein tyrosine phosphatase by hydrolyzing protein tyrosine phosphate to protein tyrosine and orthophosphate. This enzyme also hydrolyzes orthophosphoric monoesters to alcohol and orthophosphate. This gene is genetically polymorphic, and three common alleles segregating at the corresponding locus give rise to six phenotypes. Each allele appears to encode at least two electrophoretically different isozymes, Bf and Bs, which are produced in allele-specific ratios. Multiple alternatively spliced transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Aug 2008]

ACP1 links:

SH3YL1 (HGNC:29546): (SH3 and SYLF domain containing 1) Enables phosphatase binding activity and phosphatidylinositol binding activity. Predicted to act upstream of or within phosphatidylinositol biosynthetic process and regulation of ruffle assembly. Located in ruffle membrane. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Feb 15, 2023

The c.23C>T (p.S8F) alteration is located in exon 1 (coding exon 1) of the ACP1 gene. This alteration results from a C to T substitution at nucleotide position 23, causing the serine (S) at amino acid position 8 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
