X-linked lymphoproliferative disease (XLP) is a primary immunodeficiency caused by mutations in SH2D1A which encodes SAP.

A defining feature of XLP is exquisite sensitivity to infection with EBV. a B-lymphotropic virus. https://www.roneverhart.com/10-Pack-Economy-Plastic-Round-Charger-Plates-12-in-Lavender-Lilac-with-Wide-Gold-Rim-Decorative-Dinner-Party-Serving-/
