RCV003810198 | SCV004609816 | uncertain significance | Hypogonadotropic hypogonadism 2 with or without anosmia; Pfeiffer syndrome | 2023-11-24 | criteria provided, single submitter | clinical testing | This sequence change replaces leucine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 644 of the FGFR1 protein (p.Leu644Arg). 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. 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. 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. |
