APOE and Xanthelasma: With the aim of elucidating the contribution of common polymorphisms from those genes involved in lipid metabolism to the development of xanthelasma, we evaluated whether APOE (HhaI), APOB (XbaI and Ins/Del) and LDLR (AvaII and HincII) gene polymorphisms were associated with the lipid profile encountered in Brazilian individuals with xanthelasma.
