Labcorp Genetics (formerly Invitae), Labcorp RCV002232271 SCV000640016 pathogenic Diamond-Blackfan anemia; GATA binding protein 1 related thrombocytopenia with dyserythropoiesis 2017-09-03 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This variant is expected to result in a truncated GATA1 protein that lacks the N-terminal zinc-finger (residues 198-233) and C-terminal zinc-finger (residues 254-286). These domains mediate not only DNA binding, but also the majority of protein-protein interactions required for the proper transcriptional regulatory function of the GATA1 protein (PMID: 11566888, 16095949, 8628290, 15920471, 24255919). Several missense variants that result in disrupted function of the GATA1 protein have been reported in individuals affected with GATA1-related disease, indicating that loss-of-function variants in GATA1 are pathogenic (PMID: 23704091). This variant has not been reported in the literature in individuals with GATA1-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Ser8Profs*129) in the GATA1 gene. It is expected to result in an absent or disrupted protein product.
