Genes affected
ACP6 (HGNC:29609): (acid phosphatase 6, lysophosphatidic) This gene encodes a member of the histidine acid phosphatase protein family. The encoded protein hydrolyzes lysophosphatidic acid, which is involved in G protein-coupled receptor signaling, lipid raft modulation, and in balancing lipid composition within the cell. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2016]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2021The c.502C>T (p.R168W) alteration is located in exon 4 (coding exon 4) of the ACP6 gene. This alteration results from a C to T substitution at nucleotide position 502, causing the arginine (R) at amino acid position 168 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
