The purpose of this study was to determine whether frequent ABCC6 variants or hotspots exist in Japanese patients with AS.
Genomic DNA was isolated from peripheral white blood cells using a Gentra Puregene Blood Kit (Qiagen, Hilden, Germany); the DNA was used as a template for amplifying human ABCC6 genomic sequences.

ABCC6 belongs to ATP-binding cassette transporter subfamily C and encodes a 165-kDa transmembrane protein termed multi-drug resistance-associated protein (MRP) 6.
Patients were divided into 2 groups according to the type of PXE-causative mutations in the ABCC6 gene.
PXE is caused by mutations in ABCC6  (ATP-binding cassette subfamily C, member 6), a gene encoding for the multidrug resistance--associated protein 6 (MRP6), an ATP-binding cassette (ABC) transporter protein with an as-yet-unidentified function (2-7).
Cystic fibrosis is caused by mutations in CFTR (cystic fibrosis transmembrane conductance regulator), member 7 of the same ABC transporter subfamily as ABCC6. A candidate gene for PXE susceptibility is SPP1 (secreted phosphoprotein 1; previously OPN, osteopontin).
We and others have identified more than 100 PXE-associated mutations in the PXE candidate gene ABCC6
