Skin Gb3 deposits in FD patients with classical GLA mutation.

<p>Confocal microscope (x40 in A and B; x60 in C) study of Gb3 in skin vessels (A, AI and AII), sweat gland tubules (B, BI and BII) and arrector pilorum muscle (C, CI and CII). A) Skin arterioles showed no Gb3 deposits in the control subject (A). However, these abnormal deposits were abundant in the male FD patient in the wall of the arteriole and its endothelium (AII) and less evident in the female patient (AI); B) Sweat gland tubules of the control showed no Gb3 deposits (B), which were found in the male with FD (BII). The female showed nearly absent Gb3 deposits inside the sweat gland tubules (BI); C) Arrector pilorum muscle cells of the control have no Gb3 deposits (C) but they were found in the male (CII) and less in female FD patient (CI).
