Comment on list classification: Sufficient number of cases for this gene to be rated green. Confirmed with Genomics England Clinical team.Created: 19 Jun 2018, 8:54 a.m.
Asked for Genomics England clinical team input to decide if this gene should be green. Enough cases but in some only mutations in the TCF3 were looked for.Created: 14 Jun 2018, 12:11 p.m.
As noted by Olivia Niblock, in the report from Boisson et al 2013 (PMID: 24216514), although 4 unrelated individuals with agammaglobulinemia (not from isolated populations or consanguineous families) all have a de novo missense mutation in the TCF3 gene (E555K) that appears to have a dominant negative effect, only 1 patient and their family underwent whole genome sequence analysis. One other patient is reported in Ben-Ali et al 2017 (PMID: 28532655) with severe hypogammaglobulinemia who was homozygous for a nonsense mutation p.Q270*. The first cousin parents were heterozygous for this variant. Ameratunga et al 2017 (PMID: 29114388) report a mother with a de novo TCF3 mutation in addition to an inherited C104R mutation of the TACI gene. The mother has severe CVID-like disorder and systemic lupus erythematosus (SLE). Her symptomatic son, who has inherited only the TCF3 mutation, but not the TACI gene mutation, has type 1 diabetes (T1D), synovitis, reduced IgG levels and IgA deficiency. In OMIM the TCF3 gene is associated with agammaglobulinemia. No data for this gene in gene2phenotype.Created: 13 Jun 2018, 1:27 p.m.

This gene was present in the original PanelApp PID panel dataset (review in April 2018) rated as Amber. The gene is present in the 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, 10:28 a.m.

Comment on list classification: After literature research, while participants in a study in PMID: 24216514 all had the same variant, only one patient and their family had GWAS, highlighting variant in this gene. Another study in PMID 28532655 suggests a homozygous variant in an individual from a consanguineous family.Created: 15 Aug 2017, 12:54 p.m.
