Heterozygous males and females and homozygous null females are fertile and have no overt developmental defects (PubMed:16382161, PubMed:16611999, PubMed:16612000). In the small intestine mucosa and under steady-state conditions, severe reduction in the number of intraepithelial CD4+ CD8+ T-cells and, partial reduction in the number of lamina propria and intraepithelial CD8+ and CD4+ T-cells (PubMed:24687959). {ECO:0000269|PubMed:16382161, ECO:0000269|PubMed:16611999, ECO:0000269|PubMed:16612000, ECO:0000269|PubMed:24687959}. |
