Primary immunodeficiency or monogenic inflammatory bowel disease v6.12 ITPR3 Achchuthan Shanmugasundram changed review comment from: PMID:36302985 reported the identification of three different ITPR3 variants in two unrelated male patients at compound heterozygous state. The 12-year-old patient presented with combined immunodeficiency with profoundly low numbers of B and T cells and required hematopoietic stem cell transplantation (HSCT) at the age of 6 years. The 36-year-old patient resented with recurring immune thrombocytopenia (ITP), requiring splenectomy at the age of 19 years. He subsequently suffered from autoimmune hemolytic anemia, susceptibility to infections, and enteropathy. Hypogammaglobulinemia and low numbers of switched memory B cells led to a diagnosis of CVID and monthly treatment with intravenous immunoglobulin. The patient did not show signs of neuromuscular disorder. Functional work demonstrated that these variants impaired IP3-mediated Ca2+ responses in vitro, translating into deficient T-cell activation and proliferation.

PMID:39270020 reported the identification of the same ITPR3 de novo variant (p.Arg2524Cys) in four unrelated patients and they presented with a complex syndromic immunodeficiency with variable multisystemic manifestations including ectodermal dysplasia, Charcot-Marie-Tooth disease, short stature, and bone marrow failure. Functional studies in patient-derived cells and gene-edited Jurkat cell lines confirmed that this variant alone is responsible for and capable of disturbing intracellular calcium homeostasis and hence ultimately the clinical phenotype. In addition, functional work also showed that this variant exhibits a dominant-negative effect.; to: PMID:36302985 reported the identification of three different ITPR3 variants in two unrelated male patients at compound heterozygous state.

Neither monoallelic nor biallelic variants in this gene has been associated with immunodeficiency phenotypes either in OMIM or in Gene2Phenotype.

Primary immunodeficiency or monogenic inflammatory bowel disease v3.6 TLN1 Achchuthan Shanmugasundram changed review comment from: PMID:35861643 reported a 20-year old man of Mexican ancestry with a complex phenotype including thrombocytopenia, T lymphopenia, and low IgG levels. The patient had an absolute lymphocyte counts <1000/mcL and low absolute T-cells. Recent B-cell subset analysis revealed 96% naïve and 4% switched memory B-cells and initial serum immunoglobulin levels at six years of age included: IgG 273, IgA 130, IgM 36. Because of poor antibody responses to pneumococcal vaccine, he was started on immunoglobulin replacement therapy, which he has continued to the present.

He continued to experienced intermittent sinusitis, otitis media and bronchitis since 10 years of age, which cleared with oral antibiotics. At 18 years of age, he had abdominal pain at times that was diagnosed as small intestinal bacterial overgrowth, headaches often treated as migraines, and joint pain with limited signs of active arthritis.

He was identified with a de novo heterozygous variant c.685C > T (p.Pro 229 Ser) that was not present in his parents.

Added comment: Saettini et al. reviewed immunological features of Rubinstein-Taybi Syndrome and found: "Recurrent or severe infections, autoimmune/autoinflammatory complications, and lymphoproliferation were observed in 72.1%, 12.3%, and 8.2% of patients. Syndromic immunodeficiency was diagnosed in 46.4% of individuals. Despite the broad heterogeneity of immunodeficiency disorders, antibody defects were observed in 11.3% of subjects. In particular, these patients presented hypogammaglobulinemia associated with low B cell counts and reduction of switched memory B cell numbers. Immunoglobulin replacement therapy, antibiotic prophylaxis, and immunosuppressive treatment were employed in 16.4%, 8.2%, and 9.8% of patients, respectively.

Primary immunodeficiency or monogenic inflammatory bowel disease v2.266 ITCH Eleanor Williams Classified gene: ITCH as Green List (high evidence)
Primary immunodeficiency or monogenic inflammatory bowel disease v2.266 ITCH Eleanor Williams Added comment: Comment on list classification: Changed rating of gene from Red to Green. This gene was rated as Green in v2.208 and incorrectly automatically demoted to Red in v2.209. This was due to a defect in the automatic PanelApp uploading tool when a set of publications was added to the panel with the source ‘Other’, and under certain conditions associated to previous sources listed, resulted in the rating of the gene being automatically changed when it should not have been.
