Genes affected

FPR2 (HGNC:3827): (formyl peptide receptor 2) Enables amyloid-beta binding activity; scavenger receptor binding activity; and signaling receptor activity. Involved in several processes, including cellular response to amyloid-beta; positive regulation of monocyte chemotaxis; and regulation of defense response. Located in cytoplasm and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

FPR1 (HGNC:3826): (formyl peptide receptor 1) This gene encodes a G protein-coupled receptor of mammalian phagocytic cells that is a member of the G-protein coupled receptor 1 family. The protein mediates the response of phagocytic cells to invasion of the host by microorganisms and is important in host defense and inflammation.[provided by RefSeq, Jul 2010]

FPR1 Gene-Disease associations (from GenCC):

• susceptibility to localized juvenile periodontitis

  Inheritance: AR Classification: SUPPORTIVE Submitted by: Orphanet
• Tourette syndrome

  Inheritance: Unknown Classification: NO_KNOWN Submitted by: Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Uncertain_significance. The variant received 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.811
