Genes affected

CSF2RB (HGNC:2436): (colony stimulating factor 2 receptor subunit beta) The protein encoded by this gene is the common beta chain of the high affinity receptor for IL-3, IL-5 and CSF. Defects in this gene have been reported to be associated with protein alveolar proteinosis (PAP). [provided by RefSeq, Jul 2008]

The c.1107C>G (p.D369E) alteration is located in exon 9 (coding exon 8) of the CSF2RB gene. This alteration results from a C to G substitution at nucleotide position 1107, causing the aspartic acid (D) at amino acid position 369 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces aspartic acid, which is acidic and polar, with glutamic acid, which is acidic and polar, at codon 369 of the CSF2RB protein (p.Asp369Glu). This variant is present in population databases (rs139685237, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with CSF2RB-related conditions. ClinVar contains an entry for this variant (Variation ID: 504874). 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 CSF2RB protein function. 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. -

p.Asp369Glu in exon 9 of CSF2RB: This variant is not expected to have clinical s ignificance due to a lack of conservation across species, including mammals. Of note, >10 mammals have a glutamic acid at this position. In addition, computatio nal prediction tools do not suggest a high likelihood of impact to the protein. This variant has been identified in 14/126682 European chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs1396852 37). -
