UniProtKB/Swiss-Prot Q9NP73: Variant p.Lys94Glu

UDP-N-acetylglucosamine transferase subunit ALG13
Gene: ALG13
Feedback?
Variant information Variant position: help 94 The position of the amino-acid change on the UniProtKB canonical protein sequence.
Type of variant: help LP/P [Disclaimer] 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 Lysine (K) to Glutamate (E) at position 94 (K94E, p.Lys94Glu). 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 large size and basic (K) to medium size and acidic (E) The physico-chemical property of the reference and variant residues and the change implicated.
BLOSUM score: help 1 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).

Variant description: help In DEE36; disease features include abnormal isoelectric focusing of serum transferrin consistent with a glycosylation defect; enzyme activity at about 17% of wild-type; decreased N-acetylglucosaminyldiphosphodolichol N-acetylglucosaminyltransferase activity. Any additional useful information about the variant.

Sequence information Variant position: help 94 The position of the amino-acid change on the UniProtKB canonical protein sequence.
Protein sequence length: help 1137 The length of the canonical sequence.
Location on the sequence: help ADLVISHAGAGSCLETLEKG K PLVVVINEKLMNNHQLELAK 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.
