UniProtKB/Swiss-Prot P35670: Variant p.Gly626Ala

Copper-transporting ATPase 2
Gene: ATP7B
Variant information

Variant position:  626
The position of the amino-acid change on the UniProtKB canonical protein sequence.

Type of variant:  Unclassified
The variants are classified into three categories: Disease, Polymorphism and Unclassified.
  • Disease: Variants implicated in disease according to literature reports.
  • Polymorphism: Variants not reported to be implicated in disease.
  • Unclassified: Variants with uncertain implication in disease according to literature reports. Evidence against or in favor of a pathogenic role is limited and/or conflicting.

Residue change:  From Glycine (G) to Alanine (A) at position 626 (G626A, p.Gly626Ala).
Indicates the amino acid change of the variant. The one-letter and three-letter codes for amino acids used in UniProtKB/Swiss-Prot are those adopted by the commission on Biochemical Nomenclature of the IUPAC-IUB.

Physico-chemical properties:  Change from glycine (G) to small size and hydrophobic (A)
The physico-chemical property of the reference and variant residues and the change implicated.

BLOSUM score:  0
The score within a Blosum matrix for the corresponding wild-type to variant amino acid change. The log-odds score measures the logarithm for the ratio of the likelihood of two amino acids appearing by chance. The Blosum62 substitution matrix is used. This substitution matrix contains scores for all possible exchanges of one amino acid with another:
  • Lowest score: -4 (low probability of substitution).
  • Highest score: 11 (high probability of substitution).

Involvement in disease:  Wilson disease (WD) [MIM:277900]: An autosomal recessive disorder of copper metabolism in which copper cannot be incorporated into ceruloplasmin in liver, and cannot be excreted from the liver into the bile. Copper accumulates in the liver and subsequently in the brain and kidney. The disease is characterized by neurologic manifestations and signs of cirrhosis. {ECO:0000269|PubMed:10051024, ECO:0000269|PubMed:10194254, ECO:0000269|PubMed:10447265, ECO:0000269|PubMed:10453196, ECO:0000269|PubMed:10502776, ECO:0000269|PubMed:10502777, ECO:0000269|PubMed:10544227, ECO:0000269|PubMed:10721669, ECO:0000269|PubMed:10790207, ECO:0000269|PubMed:10942420, ECO:0000269|PubMed:11043508, ECO:0000269|PubMed:11093740, ECO:0000269|PubMed:11180609, ECO:0000269|PubMed:11216666, ECO:0000269|PubMed:11231950, ECO:0000269|PubMed:11243728, ECO:0000269|PubMed:11405812, ECO:0000269|PubMed:11690702, ECO:0000269|PubMed:11954751, ECO:0000269|PubMed:12325021, ECO:0000269|PubMed:12376745, ECO:0000269|PubMed:12544487, ECO:0000269|PubMed:14639035, ECO:0000269|PubMed:14966923, ECO:0000269|PubMed:14986826, ECO:0000269|PubMed:15024742, ECO:0000269|PubMed:15557537, ECO:0000269|PubMed:15811015, ECO:0000269|PubMed:15845031, ECO:0000269|PubMed:15952988, ECO:0000269|PubMed:15967699, ECO:0000269|PubMed:16088907, ECO:0000269|PubMed:16207219, ECO:0000269|PubMed:16283883, ECO:0000269|PubMed:16649058, ECO:0000269|PubMed:17718866, ECO:0000269|PubMed:17823867, ECO:0000269|PubMed:17919502, ECO:0000269|PubMed:17949296, ECO:0000269|PubMed:18203200, ECO:0000269|PubMed:18373411, ECO:0000269|PubMed:19033537, ECO:0000269|PubMed:20333758, ECO:0000269|PubMed:21398519, ECO:0000269|PubMed:21454443, ECO:0000269|PubMed:21645214, ECO:0000269|PubMed:21682854, ECO:0000269|PubMed:22075048, ECO:0000269|PubMed:22240481, ECO:0000269|PubMed:22484412, ECO:0000269|PubMed:22763723, ECO:0000269|PubMed:23159873, ECO:0000269|PubMed:23235335, ECO:0000269|PubMed:23275100, ECO:0000269|PubMed:23333878, ECO:0000269|PubMed:23518715, ECO:0000269|PubMed:23962630, ECO:0000269|PubMed:24476933, ECO:0000269|PubMed:24555712, ECO:0000269|PubMed:24706876, ECO:0000269|PubMed:25704634, ECO:0000269|PubMed:25982861, ECO:0000269|PubMed:26004889, ECO:0000269|PubMed:28856630, ECO:0000269|PubMed:7626145, ECO:0000269|PubMed:8298641, ECO:0000269|PubMed:8533760, ECO:0000269|PubMed:8782057, ECO:0000269|PubMed:8931691, ECO:0000269|PubMed:8938442, ECO:0000269|PubMed:8980283, ECO:0000269|PubMed:9222767, ECO:0000269|PubMed:9311736, ECO:0000269|PubMed:9452121, ECO:0000269|PubMed:9482578, ECO:0000269|PubMed:9554743, ECO:0000269|PubMed:9671269, ECO:0000269|PubMed:9772425, ECO:0000269|PubMed:9829905, ECO:0000269|PubMed:9837819, ECO:0000269|PubMed:9887381}.
