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]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.Arg225Cys variant in CSF2RB has not been previously reported in individual s with pulmonary disease or in large population studies. Computational predictio n tools and conservation analysis do not provide strong support for or against a n impact to the protein. In summary, the clinical significance of the p.Arg225Cy s variant is uncertain. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.673C>T (p.R225C) alteration is located in exon 6 (coding exon 5) of the CSF2RB gene. This alteration results from a C to T substitution at nucleotide position 673, causing the arginine (R) at amino acid position 225 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
