RCV000187234 | SCV000240816 | uncertain significance | not provided | 2013-09-25 | criteria provided, single submitter | clinical testing | p.Ala1192Val (GCC>GTC): c.3575 C>T in exon 22 of the CNTNAP2 gene (NM_014141.5). The Ala1192Val missense change 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 conservative substitution of one uncharged, non-polar amino acid for another. The variant alters a position in the Laminin G-like 4 domain that is conserved through placental mammals but is not conserved in more distantly related 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 Ala1192Val is a disease-causing mutation or a rare benign variant. The variant is found in EPILEPSY panel(s). |
