Interestingly, the comparative analysis of UN6 and OV6 showed that GO terms primary immunodeficiency (p = 8.82 × 10−32), B-cell receptor signaling pathway (p = 1.51 × 10−7), and Jak/STAT signaling pathway (p = 1.57 × 10−7) were enriched and specific for UN6 (age of onset <6 years) while T-cell receptor signaling pathway (p = 1.99 × 10−9) and regulation of T-cell activation (p = 8.60 × 10−6) were specific for OV6 (age of onset >6 years). The gene discussed is SOAT1; the disease is inborn error of immunity.
