Variant summary
Our verdict is Pathogenic. Variant got 27 ACMG points: 27P and 0B. PS1_Very_StrongPM1PM2PM5PP2PP3_StrongPP5_Very_Strong
The NM_000141.5(FGFR2):c.870G>T(p.Trp290Cys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. 12/20 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). Another nucleotide change resulting in same amino acid change has been previously reported as Pathogenicin ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. W290R) has been classified as Pathogenic.

Pathogenic, criteria provided, single submitter | clinical testing | 3billion | Oct 02, 2021 | Same nucleotide change resulting in same amino acid change has been previously reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000013281.1/ PMID: [PMID]). The missense variant is located in a mutational hot spot and/or well-established functional domain in which established pathogenic variants have been reported (PM1). It is not observed in the gnomAD v2.1.1 dataset (PM2). A different missense change at the same codon (p.Trp290Ser) has been reported as pathogenic (ClinVar ID:VCV000374812.1, PM5). In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.982, 3Cnet: 0.998, PP3). Patient's phenotype is considered compatible with FGFR2 related disorder (3billion dataset, PP4).Therefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline. - |

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jun 05, 2022 | For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Trp290 amino acid residue in FGFR2. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 7655462, 16418739, 20503384, 23431754, 24127277, 24656465). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 13293). This missense change has been observed in individual(s) with Pfeiffer syndrome (PMID: 9475591, 18618990, 24036790, 27683237). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces tryptophan, which is neutral and slightly polar, with cysteine, which is neutral and slightly polar, at codon 290 of the FGFR2 protein (p.Trp290Cys). - |
