Project description:Combined immunodeficiencies are a heterogeneous collection of primary immune disorders that exhibit defects in T cell development or function, along with impaired B cell activity even in light of normal B cell maturation. CARMIL2 (RLTPR) is a protein involved in cytoskeletal organization and cell migration which also plays a role in CD28 co-signaling of T cells. Mutations in this protein have recently been reported to cause a novel primary immunodeficiency disorder with variable phenotypic presentations. Here we deposit genotyping data for seven patients from three unrelated, consanguineous multiplex families that presented with dermatitis, eosophagitis and recurrent skin and chest infections with evidence of combined immunodeficiency. By using this genotyping data to perform autozygome-guided analysis, and coupling it with the results of whole exome sequencing, we uncovered two mutations not previously reported (p.R50T and p.L846Sfs) in CARMIL2.
Project description:This study reports two unrelated patients with a combined immunodeficiency. Whole-exome sequencing of both patients, their healthy parents and siblings identified in both families a /de novo/ missense variant in /ITPR3/ (NM_002224.3:c.7570C>T, p.Arg2524Cys). While the mRNA level in patients remained the same as in healthy siblings and controls, the level of protein expression was diminished. It was also shown that the ITPR3 heterozygous p.Arg2524Cys mutation impairs calcium flux function in dermal fibroblast of one patient and in a knock-in Jurkat T cell line.
