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]

The c.272A>G (p.H91R) alteration is located in exon 4 (coding exon 2) of the CSF3R gene. This alteration results from a A to G substitution at nucleotide position 272, causing the histidine (H) at amino acid position 91 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.

Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces histidine, which is basic and polar, with arginine, which is basic and polar, at codon 91 of the CSF3R protein (p.His91Arg). This variant is present in population databases (rs148307285, gnomAD 0.08%). This variant has not been reported in the literature in individuals affected with CSF3R-related conditions. ClinVar contains an entry for this variant (Variation ID: 434843). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt CSF3R 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.
