Invitae RCV001371215 SCV001567773 uncertain significance Lymphedema, primary, with myelodysplasia; Dendritic cell, monocyte, B lymphocyte, and natural killer lymphocyte deficiency 2020-03-18 criteria provided, single submitter clinical testing This sequence change replaces glycine with cysteine at codon 101 of the GATA2 protein (p.Gly101Cys). The glycine residue is moderately conserved and there is a large physicochemical difference between glycine and cysteine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with GATA2-related conditions. 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: Possibly 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.
