UniProtKB/Swiss-Prot Q8TD31: Variant p.Ala367Thr

Coiled-coil alpha-helical rod protein 1
Gene: CCHCR1
Feedback?
Variant information Variant position: help 367 The position of the amino-acid change on the UniProtKB canonical protein sequence.
Type of variant: help LB/B 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: help From Alanine (A) to Threonine (T) at position 367 (A367T, p.Ala367Thr). 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: help Change from small size and hydrophobic (A) to medium size and polar (T) The physico-chemical property of the reference and variant residues and the change implicated.
BLOSUM score: help 0 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).

Polymorphism: help HCR*WWCC is associated with susceptibility to psoriasis. Psoriasis is a chronic inflammatory dermatosis that affects approximately 2% of the population. It is a multifactorial disease characterized by red, scaly skin lesions that are usually found on the scalp, elbows, and knees, and may be associated with severe arthritis. The lesions are caused by hyperproliferative keratinocytes and infiltration of inflammatory cells into the dermis and epidermis. The usual age of onset of psoriasis is between 15 and 30 years, although it can present at any age. Association of HCR with psoriasis seem to be due to linkage disequilibrium with Cw*06:02 (PubMed:11348465). HCR is unlikely to be directly involved in psoriasis development. Additional information on the polymorphism described.

Sequence information Variant position: help 367 The position of the amino-acid change on the UniProtKB canonical protein sequence.
Protein sequence length: help 782 The length of the canonical sequence.
Location on the sequence: help QLKAQELEHSDSVKQLKGQV A SLQEKVTSQSQEQAILQRSL 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: help The multiple alignment of the region surrounding the variant against various orthologous sequences.

Sequence annotation in neighborhood: help 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.
