This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 1430 of the FLNC protein (p.Gly1430Arg). This variant also falls at the last nucleotide of exon 24, which is part of the consensus splice site for this exon. This variant has not been reported in the literature in individuals affected with FLNC-related conditions. 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. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. |
