GeneDx RCV000144747 SCV000190960 pathogenic not provided 2014-06-04 criteria provided, single submitter clinical testing The E181A 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 E181A 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. This substitution alters a highly conserved position in the protein kinase domain of the CDKL5 protein, and multiple missense mutations in nearby residues have been reported in association with CDKL5-related disorders, supporting the functional importance of this region of the protein. In silico analysis predicts this variant is probably damaging to the protein structure/function. This variant has been observed de novo without verified parentage. The variant is found in INFANT-EPI panel(s).
