1 Novel missense variants in LCAT and APOB genes in an Italian kindred with familial lecithin:cholesterol acyltransferase deficiency and hypobetalipoproteinemia  Paola Conca, PhD, Silvana Pileggi, PhD, Sara Simonelli, PhD, Emanuela Boer, MD, Giuliano Boscutti, MD, Lucia Magnolo, PhD, Patrizia Tarugi, PhD, Silvana Penco, PhD, Guido Franceschini, PhD, Laura Calabresi, PhD, Monica Gomaraschi, PhD  Journal of Clinical Lipidology  Volume 6, Issue 3, Pages (May 2012) DOI: /j.jacl Copyright © 2012 National Lipid Association Terms and Conditions

2 Figure 1 Pedigree of the family. The proband is indicated by an arrow. Left or right filled symbols indicate heterozygous carriers of LCAT (black) and apoB (gray) variants; white symbols indicate noncarrier relatives (square, male; circle, female). Slashed symbols indicate deceased individuals; N/A indicates family members not available for analysis.

3 Figure 2 Pre- and post-transplantation lipid and apolipoprotein levels. Proband’s plasma levels of HDL-C, apoA-I, and apoA-II measured during hemodialysis (pre-transplant) and 10 months after the second renal transplant (post-transplant) are shown.

4 Figure 3 Pre- and post-transplantation HDL subclass distribution. A, Plasma levels of HDL containing only apoA-I (LpA-I) and HDL containing both apoA-I and apoA-II (LpA-I:A-II) measured during hemodialysis (pre-transplant) and 10 months after the second renal transplant (post-transplant). B, Representative 2D-electrophoresis developed against apoA-I and percentage of preβ-HDL by densitometry evaluated on proband’s plasma samples collected during hemodialysis (pre-transplant) and 10 months after the second renal transplantation (post-transplant).

5 Figure 4 Pre- and post-transplantation plasma cholesterol esterification. Unesterified/total cholesterol ratio (UC/TC), plasma level of LCAT, cholesterol esterification rate (CER), and LCAT activity measured during hemodialysis (pre-transplant), and 10 months after the second renal transplant (post-transplant).
