RCV000656084 | SCV001398578 | uncertain significance | Intellectual disability, autosomal dominant 20 | 2019-10-30 | criteria provided, single submitter | clinical testing | In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This sequence change replaces serine with leucine at codon 287 of the MEF2C protein (p.Ser287Leu). The serine residue is highly conserved and there is a large physicochemical difference between serine and leucine. This variant is present in population databases (rs777826971, ExAC 0.002%). This variant has been observed in an individual with polymicrogyria, microcephaly, and tetraparesis (PMID: 29706646). It is also known as c.890C>T (p.Ser297Leu) in the literature. ClinVar contains an entry for this variant (Variation ID: 438583). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). |
