The ATP-binding cassette 6 transporter (ABCC6), one of the ABCC subfamily members, is mainly known because gene mutations are responsible for pseudoxanthoma elasticum (PXE), a rare autosomal recessive disease characterized by a progressive ectopic calcification of elastic fibers in dermal, ocular, and vascular tissues [1,2,3]. Here, ABCA3 is linked to pseudoxanthoma elasticum (inherited or acquired).
