Genes affected

FGFR2 (HGNC:3689): (fibroblast growth factor receptor 2) The protein encoded by this gene is a member of the fibroblast growth factor receptor family, where amino acid sequence is highly conserved between members and throughout evolution. FGFR family members differ from one another in their ligand affinities and tissue distribution. A full-length representative protein consists of an extracellular region, composed of three immunoglobulin-like domains, a single hydrophobic membrane-spanning segment and a cytoplasmic tyrosine kinase domain. The extracellular portion of the protein interacts with fibroblast growth factors, setting in motion a cascade of downstream signals, ultimately influencing mitogenesis and differentiation. This particular family member is a high-affinity receptor for acidic, basic and/or keratinocyte growth factor, depending on the isoform. Mutations in this gene are associated with Crouzon syndrome, Pfeiffer syndrome, Craniosynostosis, Apert syndrome, Jackson-Weiss syndrome, Beare-Stevenson cutis gyrata syndrome, Saethre-Chotzen syndrome, and syndromic craniosynostosis. Multiple alternatively spliced transcript variants encoding different isoforms have been noted for this gene. [provided by RefSeq, Jan 2009]

ACMG classification

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

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the FGFR2 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 114 curated pathogenic missense variants (we use a threshold of 10). The gene has 24 curated benign missense variants. Gene score misZ: 2.402 (below the threshold of 3.09). Trascript score misZ: 4.4365 (above the threshold of 3.09). GenCC associations: The gene is linked to Pfeiffer syndrome type 3, Crouzon syndrome, Apert syndrome, Antley-Bixler syndrome, Beare-Stevenson cutis gyrata syndrome, Jackson-Weiss syndrome, bent bone dysplasia syndrome 1, Pfeiffer syndrome, Saethre-Chotzen syndrome, LADD syndrome 1, familial scaphocephaly syndrome, McGillivray type, LADD syndrome, Pfeiffer syndrome type 1, Pfeiffer syndrome type 2, Antley-Bixler syndrome without genital anomalies or disordered steroidogenesis.
