UniProtKB/Swiss-Prot O60260: Variant p.Cys418Arg

E3 ubiquitin-protein ligase parkin
Gene: PRKN
Chromosomal location: 6q25.2-q27
Variant information

Variant position:  418
The position of the amino-acid change on the UniProtKB canonical protein sequence.

Type of variant:  Disease [Disclaimer]
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 Cysteine (C) to Arginine (R) at position 418 (C418R, p.Cys418Arg).
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 medium size and polar (C) to large size and basic (R)
The physico-chemical property of the reference and variant residues and the change implicated.

BLOSUM score:  -3
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:  Parkinson disease 2 (PARK2) [MIM:600116]: A neurodegenerative disorder characterized by bradykinesia, rigidity, postural instability, tremor, and onset usually before 40. It differs from classic Parkinson disease by early DOPA-induced dyskinesia, diurnal fluctuation of the symptoms, sleep benefit, dystonia and hyper-reflexia. Dementia is absent. Pathologically, patients show loss of dopaminergic neurons in the substantia nigra, similar to that seen in Parkinson disease; however, Lewy bodies (intraneuronal accumulations of aggregated proteins) are absent. {ECO:0000269|PubMed:10072423, ECO:0000269|PubMed:10824074, ECO:0000269|PubMed:10888878, ECO:0000269|PubMed:10939576, ECO:0000269|PubMed:11163284, ECO:0000269|PubMed:11179010, ECO:0000269|PubMed:11431533, ECO:0000269|PubMed:11487568, ECO:0000269|PubMed:11590439, ECO:0000269|PubMed:11971093, ECO:0000269|PubMed:12056932, ECO:0000269|PubMed:12112109, ECO:0000269|PubMed:12114481, ECO:0000269|PubMed:12116199, ECO:0000269|PubMed:12362318, ECO:0000269|PubMed:12397156, ECO:0000269|PubMed:12629236, ECO:0000269|PubMed:12730996, ECO:0000269|PubMed:12925569, ECO:0000269|PubMed:15584030, ECO:0000269|PubMed:17360614, ECO:0000269|PubMed:19229105, ECO:0000269|PubMed:19801972, ECO:0000269|PubMed:20404107, ECO:0000269|PubMed:20889486, ECO:0000269|PubMed:20889974, ECO:0000269|PubMed:21376232, ECO:0000269|PubMed:22956510, ECO:0000269|PubMed:9560156, ECO:0000269|PubMed:9731209}.

Sequence information

Variant position:  418
The position of the amino-acid change on the UniProtKB canonical protein sequence.

Protein sequence length:  465
The length of the canonical sequence.

Location on the sequence:   AEQARWEAASKETIKKTTKP  C PRCHVPVEKNGGCMHMKCPQ
