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]

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The p.H1329Y variant (also known as c.3985C>T), located in coding exon 23 of the FLNA gene, results from a C to T substitution at nucleotide position 3985. The histidine at codon 1329 is replaced by tyrosine, an amino acid with similar properties. Based on data from gnomAD, the T allele has an overall frequency of <0.01% (1/179057) total alleles studied, with 0 hemizygote(s) observed. The highest observed frequency was <0.01% (1/12216) of African 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. -
