CDIIB is a previous gene symbol for ITGAM. Expression evidence that ITGAM is involved in an immune response.

PMID: 29712964 An in vitro transepithelial migration assay to evaluate the role of neutrophils in Respiratory Syncytial Virus (RSV) induced epithelial damage. Neutrophils that migrated through the RSV infected airway epithelial cells (AECs) showed increased cell surface expression of CD11B and MPO compared to neutrophils that had not migrated.

PMID: 32257537 Transplantation of ACE2- Mesenchymal Stem Cells Improves the Outcome of Patients with COVID-19 Pneumonia. 7 enrolled patients were assessed for 14 days after MSC injection. After treatment, the peripheral lymphocytes were increased, the C-reactive protein decreased, and the overactivated cytokine-secreting immune cells CXCR3+CD4+ T cells, CXCR3+CD8+ T cells, and CXCR3+ NK cells disappeared in 3-6 days. In addition, a group of CD14+CD11c+CD11bmid regulatory DC cell population dramatically increased.

Although no specific gene disease evidence for ITGAM there is evidence that it is involved in the immune response and has been identified in a COVID-19 paper therefore classifying as Amber.

Comment on list classification: Changed from Amber to Red, no published cases of immunodeficiency to date. Red review from external expert review. Referred back to GRID and Victorian Clinical Genetics Services for evidences.

This gene was absent from the original PanelApp PID panel dataset (review April 2018). However it was listed in external expert immunodeficiency diagnostic gene list(s) GOSH or GRID. In this combined PID panel, this gene has been rated as AMBER and needs further curational review to assess pertinence prior to v1.
