Genes affected

BICC1 (HGNC:19351): (BicC family RNA binding protein 1) This gene encodes an RNA-binding protein that is active in regulating gene expression by modulating protein translation during embryonic development. Mouse studies identified the corresponding protein to be under strict control during cell differentiation and to be a maternally provided gene product. [provided by RefSeq, Apr 2009]

The R804H variant in the BICC1 gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The R804H variant was not observed at any significant frequency in approximately 6500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The R804H variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. This substitution occurs at a position that is conserved across species. In silico analysis predicts this variant is probably damaging to the protein structure/function. We interpret R804H as a variant of uncertain significance. -

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 804 of the BICC1 protein (p.Arg804His). This variant is present in population databases (rs372894085, gnomAD 0.009%). This variant has not been reported in the literature in individuals affected with BICC1-related conditions. ClinVar contains an entry for this variant (Variation ID: 382305). 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. 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. -
