GeneDx RCV001769246 SCV002003385 uncertain significance not provided 2020-10-12 criteria provided, single submitter clinical testing Not observed in large population cohorts (Lek et al., 2016); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
Labcorp Genetics (formerly Invitae), Labcorp RCV003772034 SCV004585775 uncertain significance Hypogonadotropic hypogonadism 2 with or without anosmia; Pfeiffer syndrome 2023-02-27 criteria provided, single submitter clinical testing This sequence change replaces valine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 636 of the FGFR1 protein (p.Val636Glu). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with FGFR1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1313295). 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 FGFR1 protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
