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.R527H variant (also known as c.1580G>A), located in coding exon 10 of the FLNA gene, results from a G to A substitution at nucleotide position 1580. The arginine at codon 527 is replaced by histidine, an amino acid with highly similar properties. Based on data from gnomAD, the A allele has an overall frequency of 0.0017% (3/181546) total alleles studied, with 1 hemizygote(s) observed. The highest observed frequency was 0.0037% (3/81313) of European (non-Finnish) alleles. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -
