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 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.772

The c.1119T>A (p.F373L) alteration is located in exon 9 (coding exon 9) of the ACP6 gene. This alteration results from a T to A substitution at nucleotide position 1119, causing the phenylalanine (F) at amino acid position 373 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
