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]
