UniProtKB/SwissProt variant VAR

Variant information

Variant position:

871

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 871 (C871R, p.Cys871Arg).

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:

Interstitial nephritis, karyomegalic (KMIN) [MIM:614817]: A rare kidney disease characterized by chronic tubulointerstitial nephritis associated with massively enlarged tubular epithelial cell nuclei. The clinical picture is associated with recurrent upper respiratory tract infections in addition to chronic kidney disease beginning in the third decade of life. {ECO:0000269|PubMed:22772369}. 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 KMIN; partially complement cell survival upon exposure to mitomycin C.

Any additional useful information about the variant.

Sequence information

Variant position:

871

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

Protein sequence length:

1017

The length of the canonical sequence.

Location on the sequence:

FMDGIPDVFRNACQAFPLDL C TDSFFTSRRPALEARLQLIH

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.

Type	Positions	Description
Chain	1 – 1017	Fanconi-associated nuclease 1
Alternative sequence	534 – 1017	Missing. In isoform 2.
Mutagenesis	864 – 864	Q -> A. Loss of nuclease activity; when associated with A-960; A-975 and A-977.
Turn	868 – 871
