Lysosomal acid lipase deficiency (LAL-D) is underrecognized because it manifests clinically with lipid and lipoprotein values similar to those observed in heterozygous familial hypercholesterolemia (FH). Although LAL-D is uncommon, understanding the differences between the 2 diseases has significant management implications. We present a case of LAL-D that masqueraded as FH. (Level of Difficulty: Advanced.).
Keywords: familial hypercholesterolemia; low-density lipoprotein cholesterol; lysosomal acid lipase deficiency; sebelipase alfa.
