Comment on list classification: There is sufficient evidence available for the promotion of this gene to green rating in the next GMS review.Created: 30 Oct 2023, 5:45 p.m. | Last Modified: 30 Oct 2023, 5:45 p.m.

PMID:25667416 - A young male with autoimmune enterocolopathy and unexplained infections revealed evidence of immunodeficiency, including IgG subclass deficiency, impaired Ag-induced lymphocyte proliferation, reduced cytokine production by CD8(+) T lymphocytes, and decreased numbers of NK cells. He was identified with 559kb deletion at 16q22.1, which contained eight genes including NFAT5 and this deletion was de novo. Inhibition or deletion of NFAT5 in normal human and murine cells also recapitulated several of the immune deficits identified in the patient.
PMID:36238298 - Two paediatric Mexican patients were identified with rare heterozygous missense variants (individual 1: c.335C>T/ p.Ser112Phe or p.Ser94Phe; individual 2: c.1291A>T/ p.Thr431Ser) and reported with Epstein-Barr virus susceptibility. One patient had chronic active EBV infection with hepatitis and enterocolitis, and the other had fatal hemophagocytic lymphohistiocytosis (HLH).
This gene has not yet been associated with any phenotypes either in OMIM or in Gene2Phenotype.Created: 30 Oct 2023, 5:44 p.m. | Last Modified: 30 Oct 2023, 5:44 p.m.

PMID: 36238298 describe two cases of pediatric Mexican patients with rare heterozygous missense variants in NFAT5 and EBV susceptibility, a school-age girl with chronic-active infection of the liver and bowel, and a teenage boy who died of hemophagocytic lymphohistiocytosis
In the discussion, they also refer to other, unpublished patients:
"Some other patients from Belarus, Ukraine, and the USA, with NFAT5 haploinsufficiency caused by heterozygous missense or small deletion variants, manifest early in life with diverse autoimmune diseases, and their T cells show reduced proliferation and survival under hypertonic conditions (Svetlana Sharapova, personal communication)"Created: 24 Oct 2023, 8:32 a.m. | Last Modified: 24 Oct 2023, 8:32 a.m.

The following PubMed IDs were added to gene NFAT5 (OMIM gene MIM#604708): 25667416. These publications have been associated with the gene by the immunedysregulation subgroup of the Human Phenotype Ontology Immune Mediated Disorders Consortium (https://hpo-immune-mediated-disorders.groups.io/g/update) in August 2020.Created: 13 Oct 2020, 9:36 a.m. | Last Modified: 13 Oct 2020, 9:36 a.m.

Comment on list classification: This rating of this gene has been returned to red. The amber rating was made in error as only one immunodeficiency associated variant has been reported in this gene.Created: 26 Sep 2018, 2:30 p.m.
Not associated with a phenotype in OMIM or in Gen2Phen. No variants reported, however, haploinsufficiency of NFAT5 was reported in young man with autoimmune enterocolopathy and unexplained infections revealing evidence of immunodeficiency, including IgG subclass deficiency, impaired Ag-induced lymphocyte proliferation, reduced cytokine production by CD8(+) T lymphocytes, and decreased numbers of NK cells (PMID 25667416).
NFAT5 is one of 8 genes (NFAT5, MIR1538, NQO1, NOB1, WWP2, MIR140, CLEC18A, and PDXDC2) located in a 559-kilobase deletion within 16q22.1 (PMID 25667416), none of the other genes appear to have any association with immunodeficiency and are not listed on this panel.
Based on this evidence in consultation with Helen Britain (Clinical Fellow, Genomics England), this gene has been promoted to amber, with a "watchlist" tag applied as it appears that changes in this gene could potentially be relevant to this panel.Created: 2 May 2018, 1:38 p.m.
watch tag added - there is supportive evidence in terms of cellular studies in mice that partially reproduce the immune phenotype with haploinsufficiency of this gene, Watchlist tag added in relation for further evidence of CNV / SNVs to promote it to green.Created: 26 Sep 2018, 2:37 p.m.
Comment on list classification: Changed from Amber to Red. Only one published case with immunodeficiency to date. Gene is pertinent on Victorian Clinical Genetics Services panel and GRID for Immunological disorders.

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.Created: 20 Apr 2018, 12:25 p.m.
