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]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.111900926).

The c.660G>C (p.Q220H) alteration is located in exon 6 (coding exon 6) of the ACP6 gene. This alteration results from a G to C substitution at nucleotide position 660, causing the glutamine (Q) at amino acid position 220 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
