Invitae RCV000655418 SCV000777348 pathogenic FGFR2 related craniosynostosis 2017-11-14 criteria provided, single submitter clinical testing This sequence change replaces tryptophan with cysteine at codon 290 of the FGFR2 protein (p.Trp290Cys). The tryptophan residue is highly conserved and there is a large physicochemical difference between tryptophan and cysteine. This variant is not present in population databases (ExAC no frequency). This variant has been reported in individuals affected with Pfeiffer syndrome (PMID: 9475591, 24036790), including individuals where the variant was confirmed to be de novo (PMID: 18618990, 27683237). ClinVar contains an entry for this variant (Variation ID: 13293). A different missense substitution at this codon (p.Trp290Arg) has been determined to be pathogenic (PMID: 7655462, 23431754, 16418739, 24656465, 24127277, 20503384). This suggests that the tryptophan residue is critical for FGFR2 protein function and that other missense substitutions at this position may also be pathogenic. For these reasons, this variant has been classified as Pathogenic.
