UniProtKB/Swiss-Prot P08709: Variant p.Asp302His

Coagulation factor VII
Gene: F7
Variant information

Variant position:  302
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 Aspartate (D) to Histidine (H) at position 302 (D302H, p.Asp302His).
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 acidic (D) to medium size and polar (H)
The physico-chemical property of the reference and variant residues and the change implicated.

BLOSUM score:  -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).

Involvement in disease:  Factor VII deficiency (FA7D) [MIM:227500]: A hemorrhagic disease with variable presentation. The clinical picture can be very severe, with the early occurrence of intracerebral hemorrhages or repeated hemarthroses, or, in contrast, moderate with cutaneous-mucosal hemorrhages (epistaxis, menorrhagia) or hemorrhages provoked by a surgical intervention. Finally, numerous subjects are completely asymptomatic despite very low factor VII levels. {ECO:0000269|PubMed:10862079, ECO:0000269|PubMed:11091194, ECO:0000269|PubMed:11129332, ECO:0000269|PubMed:12472587, ECO:0000269|PubMed:14717781, ECO:0000269|PubMed:1634227, ECO:0000269|PubMed:18976247, ECO:0000269|PubMed:19432927, ECO:0000269|PubMed:19751712, ECO:0000269|PubMed:2070047, ECO:0000269|PubMed:21206266, ECO:0000269|PubMed:21372693, ECO:0000269|PubMed:26761581, ECO:0000269|PubMed:7974346, ECO:0000269|PubMed:7981691, ECO:0000269|PubMed:8043443, ECO:0000269|PubMed:8204879, ECO:0000269|PubMed:8242057, ECO:0000269|PubMed:8364544, ECO:0000269|PubMed:8652821, ECO:0000269|PubMed:8844208, ECO:0000269|PubMed:8883260, ECO:0000269|PubMed:8940045, ECO:0000269|PubMed:9414278, ECO:0000269|PubMed:9452082, ECO:0000269|PubMed:9576180}.
