Hereditary lecithin-cholesterol acyltransferase deficiency and Bloom syndrome in the same individual

A couple who were first cousins had three children: an older son with Bloom syndrome (BLS) and homozygous lecithin-cholesterol acyltransferase (LCAT) deficiency; the second child (a son) and the parents are LCAT deficiency and the youngest child (a daughter), is homozygous for LCAT deficiency. The use of genetic markers gave no evidence of linkage of BLS and LCAT loci.
