Primary immunodeficiencyGene: KDM6A
The following PubMed IDs were added to gene KDM6A (OMIM gene MIM#300128): 23076834;22197486. These publications have been associated with the gene by the immunodeficiencies subgroup of the Human Phenotype Ontology Immune Mediated Disorders Consortium (https://hpo-immune-mediated-disorders.groups.io/g/update) in August 2020.

Comment on publications: Immunological abnormalities and KS were systematically analyzed for the first time in 2005, Hoffman JD et al. (2005) PMID:15887282. Although it was noted that no studies have analyzed in detail the functional consequences of KMT2D and KDM6A mutations on the immune system of patients with KS, and no mechanistic models accounting for such abnormalities have been proposed. Low serum immunoglobulin levels and reduced memory T and B lymphocytes have been reported Lin JL et al. (2015) PMID:25142838. Also increased occurrence of autoimmune manifestations, such as idiopathic thrombocytopenic purpura (ITP), hemolytic anemia, autoimmune thyroiditis, and vitiligo has been reported by Ming JE et al. (2005) PMID:15523604, suggests that both KMT2D and KDM6A genes may play a relevant, still undisclosed, role in the immune homeostasis.

Comment on publications: Added publications to support immunodeficiency phenotype and KS. Stagi S et al. (2016) PMID: 26411453 noted that most KS patients show increased susceptibility to infections and have reduced serum immunoglobulin levels, while some suffer also from autoimmune manifestations, such as idiopathic thrombocytopenic purpura, hemolytic anemia, autoimmune thyroiditis, and vitiligo. They reviewed the immunological aspects of KS and proposed a novel model to account for the immune dysfunction observed in this condition.

Added phenotypes Typical facial abnormalities, cleft or high arched palate, skeletal abnormalities, short stature, intellectual disability, congenital heart defects, recurrent infections (otitis media, pneumonia) in 50% of patients. Autoimmunity may be present; Combined immunodeficiencies with associated or syndromic features for gene: KDM6A Publications for gene KDM6A were updated from 26411453; 25546742; 15887282; 25142838; 15523604 to 25546742; 25142838; 32048120; 15887282; 15523604; 26411453; 32086639
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.
