UniProtKB/Swiss-Prot P23760: Variant p.Ile59Phe

Paired box protein Pax-3
Gene: PAX3
Variant information

Variant position:  59
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 Isoleucine (I) to Phenylalanine (F) at position 59 (I59F, p.Ile59Phe).
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 hydrophobic (I) to large size and aromatic (F)
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:  Waardenburg syndrome 1 (WS1) [MIM:193500]: WS1 is an autosomal dominant disorder characterized by non-progressive sensorineural deafness, pigmentary disturbances such as frontal white blaze of hair, heterochromia of irides, white eyelashes, leukoderma, and wide bridge of nose owing to lateral displacement of the inner canthus of each eye (dystopia canthorum). WS1 shows variable clinical expression and some affected individuals do not manifest hearing impairment or iris pigmentation disturbances. Dystopia canthorum is the most consistent sign and is found in 98% of the patients. {ECO:0000269|PubMed:10779847, ECO:0000269|PubMed:12949970, ECO:0000269|PubMed:1303193, ECO:0000269|PubMed:1347148, ECO:0000269|PubMed:1347149, ECO:0000269|PubMed:16971891, ECO:0000269|PubMed:20478267, ECO:0000269|PubMed:21965087, ECO:0000269|PubMed:7825605, ECO:0000269|PubMed:7833953, ECO:0000269|PubMed:7981674, ECO:0000269|PubMed:8447316, ECO:0000269|PubMed:8490648, ECO:0000269|PubMed:8533800, ECO:0000269|PubMed:8589691, ECO:0000269|PubMed:8845842, ECO:0000269|PubMed:9067759, ECO:0000269|PubMed:9452070, ECO:0000269|PubMed:9541113, ECO:0000269|Ref.35}. Note=The disease is caused by mutations affecting the gene represented in this entry.
The name and a short description of the disease associated with the variant. For more information about the disease, the user can refer to OMIM, following the link provided after the disease acronym.

Variant description:  In WS1.
Any additional useful information about the variant.

Sequence information

Variant position:  59
The position of the amino-acid change on the UniProtKB canonical protein sequence.

Protein sequence length:  479
The length of the canonical sequence.

The residue change on the sequence. Unless the variant is located at the beginning or at the end of the protein sequence, both residues upstream (20) and downstream (20) of the variant will be shown.

Sequence annotation in neighborhood:  
The regions or sites of interest surrounding the variant. In general the features listed are posttranslational modifications, binding sites, enzyme active sites, local secondary structure or other characteristics reported in the cited references. The "Sequence annotation in neighborhood" lines have a fixed format:
  • Type: the type of sequence feature.
  • Positions: endpoints of the sequence feature.
  • Description: contains additional information about the feature.
