Invitae | RCV000808036 | SCV000948120 | uncertain significance | Lymphedema, primary, with myelodysplasia; Dendritic cell, monocyte, B lymphocyte, and natural killer lymphocyte deficiency | 2019-12-13 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine with threonine at codon 342 of the GATA2 protein (p.Ala342Thr). The alanine residue is highly conserved and there is a small physicochemical difference between alanine and threonine. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the ExAC database. This variant has been observed in an individual affected with acute myeloid leukemia (PMID: 24033149). 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. |
