Variant summary

Our verdict is The variant received -4 classification points (ACGS-UK Somatic Oncogenicity v2025). B1_Strong

The NM_000141.5(FGFR2):c.109+7033T>C variant causes a intron change involving the alteration of a non-conserved nucleotide. The gene FGFR2 is a tumor suppressor gene (CancerMine: 5 TSG, 46 oncogene, 36 driver citations). The gene FGFR2 is a known oncogene (CancerMine: 5 TSG, 46 oncogene, 36 driver citations). The gene FGFR2 is a cancer driver gene (CancerMine: 5 TSG, 46 oncogene, 36 driver citations). The variant allele was found at a cumulative frequency of 0.408 (AC=62,074) in the gnomAD database across 152,050 control chromosomes, including 12,688 homozygotes. The grpmax filtering allele frequency (95% CI) is 0.421. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Benign/Likely Benign (★).

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]
