This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with Pfeiffer syndrome (Invitae). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt FGFR2 protein function. This variant disrupts the p.Glu565 amino acid residue in FGFR2. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 11781872, 15523615, 18541976, 24127277). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. (less)
