The lymphocyte subpopulation showed CD4 lymphopenia (212 cells/uL) and significant reduction in B cells (193 cells/uL) with normal NK cells count (1211 cells/uL); the majority of T cells receptors showed abnormal gamma/delta receptors, which can be seen in Omenn syndrome and hypomorphic RAGI/II mutation. Here, CD4 is linked to lymphopenia.
