Labcorp Genetics (formerly Invitae), Labcorp RCV000477547 SCV000551860 uncertain significance Atrial septal defect 7 2018-05-15 criteria provided, single submitter clinical testing This sequence change replaces proline with leucine at codon 275 of the NKX2-5 protein (p.Pro275Leu). The proline residue is moderately conserved and there is a moderate physicochemical difference between proline and leucine. While this variant is not present in population databases (ExAC no frequency), the frequency information is unreliable, as metrics indicate poor data quality at this position in the ExAC database. This variant has not been reported in the literature in an individual with a NKX2-5-related disease. ClinVar contains an entry for this variant (Variation ID: 410967). Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). In summary, this variant is a rare missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance.
