Labcorp Genetics (formerly Invitae), Labcorp RCV001935102 SCV002172884 uncertain significance Hypogonadotropic hypogonadism 2 with or without anosmia; Pfeiffer syndrome 2024-01-22 criteria provided, single submitter clinical testing This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 816 of the FGFR1 protein (p.Asn816Ser). 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: 1401450). 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.
