Centre for Mendelian Genomics, University Medical Centre Ljubljana RCV001197889 SCV001368672 uncertain significance Cardiac valvular dysplasia, X-linked 2016-01-01 criteria provided, single submitter clinical testing This variant was classified as: Uncertain significance. The following ACMG criteria were applied in classifying this variant: PM2.
Labcorp Genetics (formerly Invitae), Labcorp RCV001241517 SCV001414540 uncertain significance Heterotopia, periventricular, X-linked dominant; Melnick-Needles syndrome; Oto-palato-digital syndrome, type II; Frontometaphyseal dysplasia 2025-01-19 criteria provided, single submitter clinical testing This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 1231 of the FLNA protein (p.Val1231Ile). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with FLNA-related conditions. ClinVar contains an entry for this variant (Variation ID: 931380). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt FLNA protein function with a negative predictive value of 95%. 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.
