Variant information Variant position:

26 The position of the amino-acid change on the UniProtKB canonical protein sequence.
Type of variant:

US The variants are classified into three categories: LP/P, LB/B and US.

LP/P: likely pathogenic or pathogenic.
LB/B: likely benign or benign.
US: uncertain significance

Residue change:

From Cysteine (C) to Phenylalanine (F) at position 26 (C26F, p.Cys26Phe). 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 aromatic (F) 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).

Variant description:

In CONDSIAS; uncertain significance; reduced protein abundance; increased levels of ADP-ribose; May result in protein misfolding or aggregation. Any additional useful information about the variant.

Sequence information Variant position:

26 The position of the amino-acid change on the UniProtKB canonical protein sequence.
Protein sequence length:

363 The length of the canonical sequence.
Location on the sequence:

MAAAAGGGAGAARSLSRFRG C LAGALLGDCVGSFYEAHDTV 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 – 363	ADP-ribosylhydrolase ARH3
Binding site	41 – 41
Site	41 – 41	Glutamate flap
Mutagenesis	34 – 34	D -> G. Reduces hydrolase activity.
Mutagenesis	41 – 41	E -> AQ. Significant loss of activity. Does not affect recruitment to DNA lesion regions following DNA damage. Strongly reduced ability to hydrolyze proteins ADP-ribosylated on serine.
Helix	19 – 42
