Genes affected

GFI1 (HGNC:4237): (growth factor independent 1 transcriptional repressor) This gene encodes a nuclear zinc finger protein that functions as a transcriptional repressor. This protein plays a role in diverse developmental contexts, including hematopoiesis and oncogenesis. It functions as part of a complex along with other cofactors to control histone modifications that lead to silencing of the target gene promoters. Mutations in this gene cause autosomal dominant severe congenital neutropenia, and also dominant nonimmune chronic idiopathic neutropenia of adults, which are heterogeneous hematopoietic disorders that cause predispositions to leukemias and infections. Multiple alternatively spliced variants, encoding the same protein, have been identified for this gene. [provided by RefSeq, Jul 2008]

Likely benign, criteria provided, single submitter	clinical testing	Mendelics	May 28, 2019	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	May 30, 2023	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. 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 GFI1 protein function. ClinVar contains an entry for this variant (Variation ID: 8740). This missense change has been observed in individual(s) with neutropenia (PMID: 12778173). This variant is present in population databases (rs28936382, gnomAD 0.004%). This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 403 of the GFI1 protein (p.Lys403Arg). -
