Genes affected

CSF3R (HGNC:2439): (colony stimulating factor 3 receptor) The protein encoded by this gene is the receptor for colony stimulating factor 3, a cytokine that controls the production, differentiation, and function of granulocytes. The encoded protein, which is a member of the family of cytokine receptors, may also function in some cell surface adhesion or recognition processes. Alternatively spliced transcript variants have been described. Mutations in this gene are a cause of Kostmann syndrome, also known as severe congenital neutropenia. [provided by RefSeq, Aug 2010]

This sequence change replaces proline, which is neutral and non-polar, with histidine, which is basic and polar, at codon 229 of the CSF3R protein (p.Pro229His). This variant is present in population databases (rs764202764, gnomAD 0.01%). This missense change has been observed in individual(s) with severe congenital neutropenia (PMID: 10449521). This variant is also known as 850C>A or Pro206His. ClinVar contains an entry for this variant (Variation ID: 570209). 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 expected to disrupt CSF3R protein function. Experimental studies have shown that this missense change affects CSF3R function (PMID: 10449521). 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. -
