RCV000423143 | SCV000513934 | uncertain significance | not specified | 2016-02-16 | criteria provided, single submitter | clinical testing | The E660G variant in the NIPBL gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The E660G variant was not observed 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. This substitution occurs at a position that is conserved across mammalian species. The E660G variant is also a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. However, in silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. We interpret E660G as a variant of uncertain significance. |
