Variant summary
Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PVS1PM2PP5_Moderate
The NM_001110556.2(FLNA):c.3529G>T(p.Glu1177Ter) variant causes a stop gained change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Variant results in nonsense mediated mRNA decay.

Genes affected
FLNA (HGNC:3754): (filamin A) The protein encoded by this gene is an actin-binding protein that crosslinks actin filaments and links actin filaments to membrane glycoproteins. The encoded protein is involved in remodeling the cytoskeleton to effect changes in cell shape and migration. This protein interacts with integrins, transmembrane receptor complexes, and second messengers. Defects in this gene are a cause of several syndromes, including periventricular nodular heterotopias (PVNH1, PVNH4), otopalatodigital syndromes (OPD1, OPD2), frontometaphyseal dysplasia (FMD), Melnick-Needles syndrome (MNS), and X-linked congenital idiopathic intestinal pseudoobstruction (CIIPX). Two transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Mar 2009]

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | May 09, 2019 | For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in FLNA are known to be pathogenic (PMID: 16684786, 20730588, 26471271). This variant has not been reported in the literature in individuals with FLNA-related conditions. ClinVar contains an entry for this variant (Variation ID: 533562). This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Glu1177*) in the FLNA gene. It is expected to result in an absent or disrupted protein product. - |
