p.Thr213Ala (ACT>GCT): c.637 A>G in exon 7 of the LIAS gene (NM_006859.2). The Thr213Ala missense change in the LIAS gene 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. This variant is a non-conservative amino acid substitution of a polar Threonine residue with a non-polar Alanine residue at a position that is highly conserved across species. In silico analysis is inconsistent with regard to the effect this variant may have on the protein structure/function. Therefore, based on the currently available information, it is unclear whether Thr213Ala is a disease-causing mutation or a rare benign variant. The variant is found in INFANT-EPI,EPILEPSY panel(s).
