GeneDx RCV001576834 SCV001804095 uncertain significance not provided 2019-11-19 criteria provided, single submitter clinical testing Not observed in large population cohorts (Lek et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
Labcorp Genetics (formerly Invitae), Labcorp RCV002300555 SCV002591471 uncertain significance Heterotopia, periventricular, X-linked dominant; Melnick-Needles syndrome; Oto-palato-digital syndrome, type II; Frontometaphyseal dysplasia 2022-08-02 criteria provided, single submitter clinical testing 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) performed at Invitae indicates that this missense variant is not expected to disrupt FLNA protein function. ClinVar contains an entry for this variant (Variation ID: 1208486). This variant has not been reported in the literature in individuals affected with FLNA-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces histidine, which is basic and polar, with glutamine, which is neutral and polar, at codon 457 of the FLNA protein (p.His457Gln).
