RCV001948853 | SCV002215430 | uncertain significance | Hypogonadotropic hypogonadism 2 with or without anosmia; Pfeiffer syndrome | 2021-06-22 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (ExAC no frequency). This sequence change replaces glutamine with arginine at codon 574 of the FGFR1 protein (p.Gln574Arg). The glutamine residue is moderately conserved and there is a small physicochemical difference between glutamine and arginine. This variant has not been reported in the literature in individuals with FGFR1-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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. |
