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]

CSF2RB Gene-Disease associations (from GenCC):

• surfactant metabolism dysfunction, pulmonary, 5

  Inheritance: AR Classification: MODERATE, LIMITED Submitted by: Labcorp Genetics (formerly Invitae), Ambry Genetics
• hereditary pulmonary alveolar proteinosis

  Inheritance: AR Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.001964748).
• BP6: Variant 22-36930401-G-C is Benign according to our data. Variant chr22-36930401-G-C is described in ClinVar as Benign. ClinVar VariationId is 226555.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.208 is higher than 0.05.
