UniProtKB/Swiss-Prot Q01974: Variant p.Arg189Trp

Tyrosine-protein kinase transmembrane receptor ROR2
Gene: ROR2
Variant information

Variant position:  189
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 Arginine (R) to Tryptophan (W) at position 189 (R189W, p.Arg189Trp).
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 large size and basic (R) to large size and aromatic (W)
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:  Robinow syndrome autosomal recessive (RRS) [MIM:268310]: A recessive form of Robinow syndrome, a disease characterized by short-limb dwarfism, costovertebral segmentation defects and abnormalities of the head, face and external genitalia. The clinical signs are generally far more severe in recessive cases, particularly skeletal abnormalities. All patients with the recessive form suffer from vertebral segmentation abnormalities, resulting in scoliosis and chest deformities. Rib fusions are considered to be characteristic of the autosomal recessive form. Patients can also present brachydactyly, with extensive aplasia/hypoplasia of the phalanges and metacarpals/metatarsals, and brachy-syn-polydactyly of the hands and oligodactyly of the feet. {ECO:0000269|PubMed:10932186, ECO:0000269|PubMed:10932187}. Note=The disease is caused by mutations affecting the gene represented in this entry.

Sequence information

Variant position:  189
The position of the amino-acid change on the UniProtKB canonical protein sequence.

Protein sequence length:  943
The length of the canonical sequence.

Location on the sequence:   HEDGFCQPYRGIACARFIGN  R TIYVDSLQMQGEIENRITAA
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.
