Invitae | RCV000691681 | SCV000819470 | uncertain significance | Lymphedema, primary, with myelodysplasia; Dendritic cell, monocyte, B lymphocyte, and natural killer lymphocyte deficiency | 2019-11-10 | criteria provided, single submitter | clinical testing | This sequence change replaces threonine with methionine at codon 457 of the GATA2 protein (p.Thr457Met). The threonine residue is moderately conserved and there is a moderate physicochemical difference between threonine and methionine. This variant is present in population databases (rs139415862, ExAC 0.009%). This variant has not been reported in the literature in individuals with GATA2-related conditions. ClinVar contains an entry for this variant (Variation ID: 570747). 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: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. |
