ATP7B codes for a protein that transports copper out of cells. Varied defects (over 20 distinct mutations) in ATP7B are associated with Wilson's disease [PMID 15523622]. The specific mutation affects the ceruloplasmin level, severity, and age of onset [PMID 16283883].

More than 800 pathogenic variants have been identified (see the Wilson Disease Mutation Database), although less than 200 are currently listed in ClinVar, and many lack dbSNP rs-ids. The most frequent ATP7B pathogenic variants in two different populations are:

  • In Europeans: rs76151636, aka p.His1069Gln, occurring at a frequency of 26%-70% in Wilson patient populations and associated with neurologic or hepatic disease and a mean onset age of about 20 years.
  • In Asians: rs28942074, aka p.Arg778Leu, found at a frequency of about 10- 30% in all Chinese, Korean and Japanese Wilson patient populations studied.


Other mutations associated with Wilson's include:

  • p.Ala982Thr [PMID 24476933 ]
  • -36C-->T
  • Trp650ter
  • Gln914ter
  • 2810delT
  • Thr935Met
  • Arg1041Pro
  • Glu1173Lys
  • 1168A-->G (Ile390Val)
  • 2785A-->G (Ile929Val)
  • 3316G-->A (Val1106Ile)
  • Thr935Met. [PMID 11405812]

Arg778Leu and Thr935Met accounted for almost half of Chinese Wilson's patients in one study. [PMID 11405812]
