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]

Collection Method: clinical testing

The c.784C>T (p.H262Y) alteration is located in exon 7 (coding exon 7) of the ACP6 gene. This alteration results from a C to T substitution at nucleotide position 784, causing the histidine (H) at amino acid position 262 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
