Reporter gene analysis indicated that the rs3088442 G allele might suppress miR-147a binding to the 3' untranslated region of SLC22A3, resulting in altered SLC22A3 and LPA gene expression (P=0.015 and 9.2×10(-6), respectively), possibly explaining the increased plasma Lp(a) levels and risk of CAD.
A solute carrier family 22 member 3 variant rs3088442 G→A associated with coronary heart disease inhibits lipopolysaccharide-induced inflammatory response.
Relatively low numbers of kringle 4 type 2 repeats in apolipoprotein(a) and specific haplotypes of the SLC22A3-LPAL2-LPA region on chromosome 6 are associated with an increased risk of coronary disease.
