UniProtKB/Swiss-Prot P01130: Variant p.Cys95Gly

Low-density lipoprotein receptor
Gene: LDLR
Variant information

Variant position:  95
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 Cysteine (C) to Glycine (G) at position 95 (C95G, p.Cys95Gly).
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 glycine (G)
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:  Familial hypercholesterolemia (FH) [MIM:143890]: A common autosomal dominant disorder characterized by elevated serum low-density lipoprotein (LDL) cholesterol levels, which result in excess deposition of cholesterol in tissues and leads to xanthelasma, xanthomas, accelerated atherosclerosis and increased risk of premature coronary heart disease. The disorder occurs in 2 clinical forms: a mild form that becomes evident in the fourth or fifth decade in individuals carrying heterozygous LDLR mutations; a more severe form that usually manifests in the first two decades of life in individuals with homozygous LDLR mutations. {ECO:0000269|PubMed:10090484, ECO:0000269|PubMed:10206683, ECO:0000269|PubMed:10422803, ECO:0000269|PubMed:10447263, ECO:0000269|PubMed:10532689, ECO:0000269|PubMed:10660340, ECO:0000269|PubMed:10882754, ECO:0000269|PubMed:10978268, ECO:0000269|PubMed:10980548, ECO:0000269|PubMed:11298688, ECO:0000269|PubMed:11462246, ECO:0000269|PubMed:1446662, ECO:0000269|PubMed:1464748, ECO:0000269|PubMed:17142622, ECO:0000269|PubMed:17347910, ECO:0000269|PubMed:1867200, ECO:0000269|PubMed:19318025, ECO:0000269|PubMed:19319977, ECO:0000269|PubMed:22160468, ECO:0000269|PubMed:22509010, ECO:0000269|PubMed:2318961, ECO:0000269|PubMed:24529145, ECO:0000269|PubMed:25378237, ECO:0000269|PubMed:25545329, ECO:0000269|PubMed:2569482, ECO:0000269|PubMed:2726768, ECO:0000269|PubMed:3263645, ECO:0000269|PubMed:3955657, ECO:0000269|PubMed:7550239, ECO:0000269|PubMed:7573037, ECO:0000269|PubMed:7583548, ECO:0000269|PubMed:7635461, ECO:0000269|PubMed:7635482, ECO:0000269|PubMed:7649546, ECO:0000269|PubMed:7649549, ECO:0000269|PubMed:8168830, ECO:0000269|PubMed:8347689, ECO:0000269|PubMed:8462973, ECO:0000269|PubMed:8664907, ECO:0000269|PubMed:8740918, ECO:0000269|PubMed:9026534, ECO:0000269|PubMed:9104431, ECO:0000269|PubMed:9143924, ECO:0000269|PubMed:9254862, ECO:0000269|PubMed:9259195, ECO:0000269|PubMed:9452094, ECO:0000269|PubMed:9452095, ECO:0000269|PubMed:9452118, ECO:0000269|PubMed:9654205, ECO:0000269|PubMed:9678702, ECO:0000269|PubMed:9852677, ECO:0000269|Ref.71}.
