RCV000445207 | SCV000535060 | uncertain significance | not provided | 2016-12-19 | criteria provided, single submitter | clinical testing | A variant of uncertain significance has been identified in the LDB3 gene. The R85C variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. R85C was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, and it was not observed with any significant frequency in the Exome Aggregation Consortium (ExAC). The R85C variant is 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. Moreover, this substitution occurs at a position that is conserved across species, and in silico analysis predicts this variant is probably damaging to the protein structure/function. Nevertheless, no pathogenic missense variants in nearby residues have been reported in the Human Gene Mutation Database (Stenson et al., 2014), indicating that this region of the gene is not known to harbor disease-causing variants.Therefore, based on the currently available information, it is unclear whether this variant is pathogenic or rare benign. This result cannot be interpreted for diagnosis or used for family member screening at this time. |
