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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 05, 2023The c.769G>A (p.A257T) alteration is located in exon 6 (coding exon 6) of the ACP6 gene. This alteration results from a G to A substitution at nucleotide position 769, causing the alanine (A) at amino acid position 257 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
