Genes affected

GATA1 (HGNC:4170): (GATA binding protein 1) This gene encodes a protein which belongs to the GATA family of transcription factors. The protein plays an important role in erythroid development by regulating the switch of fetal hemoglobin to adult hemoglobin. Mutations in this gene have been associated with X-linked dyserythropoietic anemia and thrombocytopenia. [provided by RefSeq, Jul 2008]

Diamond-Blackfan anemia;C1845837:GATA binding protein 1 related thrombocytopenia with dyserythropoiesis

Uncertain:1

Apr 17, 2024

Labcorp Genetics (formerly Invitae), Labcorp

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 140 of the GATA1 protein (p.Arg140Gln). This variant is present in population databases (no rsID available, gnomAD 0.001%), including at least one homozygous and/or hemizygous individual. This variant has not been reported in the literature in individuals affected with GATA1-related conditions. ClinVar contains an entry for this variant (Variation ID: 533694). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt GATA1 protein function with a negative predictive value of 80%. 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. -
