Associated with Immunodeficiency 49 #617237 (AD) in OMIM.
PMID: 29985992 - Lessel et al 2018 - identified de novo heterozygous germline mutations in BCL11B in nine unrelated patients, namely six frameshift, two nonsense and one missense mutation. A further patient inherited a heterozygous frameshift mutation, p.(Asp534Thrfs*29), transmitted from an affected mother with. All analysed individuals exhibited developmental delay and intellectual disability and a severe reduction of peripheral ILC2s and impaired T cell development, but no overt immune deficiency. Patient E:II-1, with a missense variant, was the only patient with suspected immunodeficiency diagnosed upon newborn screening. Other de-novo variants were also detected in some patients.
PMID: 27959755 - Punwani et al 2016 - an infant with "leaky" SCID as well as craniofacial and dermal abnormalities and the absence of a corpus callosum. Exome sequencing revealed a heterozygous de novo missense mutation, p.N441K, in BCL11B. The mutant protein had dominant negative activity, which prevented the wild-type BCL11B to bind DNA, thereby arresting development of the T-cell lineage and disrupting hematopoietic stem-cell migration. bcl11ba-deficient zebrafish recapitulated the phenotype.Created: 22 Apr 2020, 5:57 p.m. | Last Modified: 22 Apr 2020, 5:58 p.m.

2018-07-12 Louise Daugherty (Genomics England Curator) promoted panel to v1.0. Reviews were assessed, and panel was revised according to expert reviews and further in-house curation based on PanelApp guidelines. Previous panels (A- or hypo-gammaglobulinaemia, Congenital neutropaenia, Agranulocytosis, Combined B and T cell defect, Inherited complement deficiency and SCID panels) that were merged with this panel, were checked again for any changes/new reviews prior to versioning of this panel, these merged panels are now retired/made internal.
Gene: bcl11b has been classified as Red List (Low Evidence).
