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]

Classification made for transcript
Verdict is Pathogenic. Variant got 14 ACMG points.
PVS1
?
Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant located near the start codon (<100nt), not predicted to undergo nonsense mediated mRNA decay. There are 49 pathogenic variants in the truncated region.
PS1
?
Another start lost variant in NM_002049.4 (GATA1) was described as [Pathogenic] in ClinVar as 1068653
PM2
?
Very rare variant in population databases, with high coverage;
PP5
?
Variant X-48791111-T-TG is Pathogenic according to our data. Variant chrX-48791111-T-TG is described in ClinVar as [Pathogenic]. Clinvar id is 998065.Status of the report is criteria_provided_single_submitter, 1 stars.
