UniProtKB/Swiss-Prot P04637: Variant p.Arg290His

Cellular tumor antigen p53
Gene: TP53
Chromosomal location: 17p13.1
Variant information

Variant position:  290
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 Arginine (R) to Histidine (H) at position 290 (R290H, p.Arg290His).
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 large size and basic (R) to medium size and polar (H)
The physico-chemical property of the reference and variant residues and the change implicated.

BLOSUM score:  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).

Involvement in disease:  Li-Fraumeni syndrome (LFS) [MIM:151623]: An autosomal dominant familial cancer syndrome that in its classic form is defined by the existence of a proband affected by a sarcoma before 45 years with a first degree relative affected by any tumor before 45 years and another first degree relative with any tumor before 45 years or a sarcoma at any age. Other clinical definitions for LFS have been proposed and called Li-Fraumeni like syndrome (LFL). In these families affected relatives develop a diverse set of malignancies at unusually early ages. Four types of cancers account for 80% of tumors occurring in TP53 germline mutation carriers: breast cancers, soft tissue and bone sarcomas, brain tumors (astrocytomas) and adrenocortical carcinomas. Less frequent tumors include choroid plexus carcinoma or papilloma before the age of 15, rhabdomyosarcoma before the age of 5, leukemia, Wilms tumor, malignant phyllodes tumor, colorectal and gastric cancers. {ECO:0000269|PubMed:10484981, ECO:0000269|PubMed:1565144, ECO:0000269|PubMed:1737852, ECO:0000269|PubMed:1933902, ECO:0000269|PubMed:1978757, ECO:0000269|PubMed:2259385, ECO:0000269|PubMed:7887414, ECO:0000269|PubMed:8825920, ECO:0000269|PubMed:9452042}.

Sequence information

Variant position:  290
The position of the amino-acid change on the UniProtKB canonical protein sequence.

Protein sequence length:  393
The length of the canonical sequence.

Location on the sequence:   FEVRVCACPGRDRRTEEENL  R KKGEPHHELPPGSTKRALPN
