UniProtKB/SwissProt variant VAR

Variant information

Variant position:

127

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 Histidine (H) to Proline (P) at position 127 (H127P, p.His127Pro).

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 (H) to medium size and hydrophobic (P)

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:

Papillon-Lefevre syndrome (PLS) [MIM:245000]: An autosomal recessive disorder characterized by palmoplantar keratosis and severe periodontitis affecting deciduous and permanent dentitions and resulting in premature tooth loss. The palmoplantar keratotic phenotype vary from mild psoriasiform scaly skin to overt hyperkeratosis. Keratosis also affects other sites such as elbows and knees. {ECO:0000269|PubMed:10581027, ECO:0000269|PubMed:10662808, ECO:0000269|PubMed:11106356, ECO:0000269|PubMed:11158173, ECO:0000269|PubMed:11180012, ECO:0000269|PubMed:11180601, ECO:0000269|PubMed:11886537, ECO:0000269|PubMed:12112662, ECO:0000269|PubMed:12809647, ECO:0000269|PubMed:14974080, ECO:0000269|PubMed:15108292, ECO:0000269|PubMed:15991336, ECO:0000269|PubMed:25799584}. Note=The disease is caused by mutations affecting the gene represented in this entry.

Sequence information

Variant position:

127

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

Protein sequence length:

463

The length of the canonical sequence.

Location on the sequence:

YKEEGSKVTTYCNETMTGWV H DVLGRNWACFTGKKVGTASE

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.
