Intriguingly, a previous study showed how European Roma carried higher frequencies of SNPs involved in hyperlipidemia (Mendizabal et al. 2013); we found one deletion in RHCE gene in linkage with one cholesterol-associated SNP within the neighboring MACO1 gene (however, a direct functional effect upon the RHCE gene, which codes for a Rh-like red blood cell antigen, should not be dismissed), and indeed the deletion is higher in frequency within Roma. Here, MACO1 is linked to hyperlipidemia.
