FOXI3 haploinsufficiency contributes to low T-cell receptor excision circles and T-cell lymphopenia.

ABSTRACT:

Background

Newborn screening can identify neonatal T-cell lymphopenia through detection of a low number of copies of T-cell receptor excision circles in dried blood spots collected at birth. After a positive screening result, further diagnostic testing is required to determine whether the subject has severe combined immunodeficiency or other causes of T-cell lymphopenia. Even after thorough evaluation, approximately 15% of children with a positive result of newborn screening for T-cell receptor excision circles remain genetically undiagnosed. Identifying the underlying genetic etiology is necessary to guide subsequent clinical management and family planning.

Objective

We sought to elucidate the genetic basis of patients with T-cell lymphopenia without an apparent genetic dia
