RCV000712051 | SCV000241392 | uncertain significance | not provided | 2014-07-25 | criteria provided, single submitter | clinical testing | This variant is denoted p.Ser254Ala (TCC>GCC): c.760 T>G in exon 2 of the KANSL1 gene (NM_001193466.1). The S254A variant has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. It was not observed in approximately 6,500 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 S254A 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. However, this substitution occurs at a position that is not conserved across species, and in silico analysis predicts this variant likely does not alter the protein structure/function. In addition, missense mutations have not been reported in association with epilepsy. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic mutation or a rare benign variant. The variant is found in CHILD-EPI panel(s). |
