UniProtKB/Swiss-Prot P04150: Variant p.Ile559Asn

Glucocorticoid receptor
Gene: NR3C1
Variant information

Variant position:  559
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 Isoleucine (I) to Asparagine (N) at position 559 (I559N, p.Ile559Asn).
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 hydrophobic (I) to medium size and polar (N)
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:  Glucocorticoid resistance, generalized (GCCR) [MIM:615962]: An autosomal dominant disease characterized by increased plasma cortisol concentration and high urinary free cortisol, resistance to adrenal suppression by dexamethasone, and the absence of Cushing syndrome typical signs. Clinical features include hypoglycemia, hypertension, metabolic alkalosis, chronic fatigue and profound anxiety. {ECO:0000269|PubMed:11589680, ECO:0000269|PubMed:11701741, ECO:0000269|PubMed:12050230, ECO:0000269|PubMed:15769988, ECO:0000269|PubMed:1704018, ECO:0000269|PubMed:17635946, ECO:0000269|PubMed:20335448, ECO:0000269|PubMed:21362280, ECO:0000269|PubMed:23426617, ECO:0000269|PubMed:24483153, ECO:0000269|PubMed:26031419, ECO:0000269|PubMed:26541474, ECO:0000269|PubMed:27120390, ECO:0000269|PubMed:7683692}. 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 GCCR; interferes with translocation to the nucleus and thereby strongly reduces transcription activation; is equally impaired in nuclear export; acts as dominant negative mutant.

Sequence information

Variant position:  559
The position of the amino-acid change on the UniProtKB canonical protein sequence.

Protein sequence length:  777
The length of the canonical sequence.

Location on the sequence:   IEPEVLYAGYDSSVPDSTWR  I MTTLNMLGGRQVIAAVKWAK
