UniProtKB/Swiss-Prot Q92781: Variant p.Gly107Arg

11-cis retinol dehydrogenase
Gene: RDH5
Chromosomal location: 12q13-q14
Variant information

Variant position:  107
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 Glycine (G) to Arginine (R) at position 107 (G107R, p.Gly107Arg).
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 large size and basic (R)
The physico-chemical property of the reference and variant residues and the change implicated.

BLOSUM score:  -2
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:  Fundus albipunctatus (FALBI) [MIM:136880]: A form of fleck retina disease characterized by discrete uniform white dots over the entire fundus with greatest density in the mid-periphery and no macular involvement. Night blindness occurs. Inheritance can be autosomal dominant or autosomal recessive. {ECO:0000269|PubMed:10369264, ECO:0000269|PubMed:10617778, ECO:0000269|PubMed:11053295, ECO:0000269|PubMed:11053296, ECO:0000269|PubMed:11078852, ECO:0000269|PubMed:11470705, ECO:0000269|PubMed:11675386, ECO:0000269|PubMed:12788147, ECO:0000269|PubMed:12967826, ECO:0000269|PubMed:25820994}. 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 FALBI; associated with macular dystrophy.
Any additional useful information about the variant.

Sequence information

Variant position:  107
The position of the amino-acid change on the UniProtKB canonical protein sequence.

Protein sequence length:  318
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.

Residue conservation: 
The multiple alignment of the region surrounding the variant against various orthologous sequences.




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.
