Molecular assessment of thymic capacities in patients with Schimke immuno-osseous dysplasia

Schimke immuno-osseous dysplasia (SIOD) is caused by SMARCAL1 deficiency and characterized by defective T-cell immunity. The immunodeficiency and the role of thymic function in SIOD patients are not clearly understood. We performed thymic evaluations by assessing T-cell receptor (TCR) diversity, rearrangement, and excision circles in family members with different disease severity carrying the same bi-allelic mutation and in a heterozygous...
