Invitae RCV003808601 SCV004592682 uncertain significance Hypogonadotropic hypogonadism 2 with or without anosmia; Pfeiffer syndrome 2023-03-27 criteria provided, single submitter clinical testing This sequence change replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 220 of the FGFR1 protein (p.Val220Leu). 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. 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on FGFR1 protein function. This variant has not been reported in the literature in individuals affected with FGFR1-related conditions. This variant is not present in population databases (gnomAD no frequency).
