This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 11 of the ZNF341 protein (p.Gly11Arg). This variant also falls at the last nucleotide of exon 1, which is part of the consensus splice site for this exon. This variant is present in population databases (no rsID available, gnomAD no frequency). This variant has not been reported in the literature in individuals affected with ZNF341-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C15". The arginine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. 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. -
