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]

The p.R2234Q variant (also known as c.6701G>A), located in coding exon 39 of the FLNA gene, results from a G to A substitution at nucleotide position 6701. The arginine at codon 2234 is replaced by glutamine, an amino acid with highly similar properties. Based on data from gnomAD, the A allele has an overall frequency of 0.002% (3/178731) total alleles studied, with 1 hemizygote(s) observed. The highest observed frequency was 0.01% (2/13480) of East Asian alleles. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
