Examples of use of VariO terms for annotation of variations and their effects

 

Missense variation


Missense variation g>a in sequence EMBL: U78027: at position 62789 leading to G302E substitution (BTKBase entry A0165) causing X-linked agammaglobulinemia (Hageman T. et al. Hum Mut. 1995).

The effects of the variant were investigated in expressed SH2 domain of the protein and found to affect protein structure accoding CD spectroscopy, binding to substrate according to pY-Sepharose binding (Mattsson et al. J. Immunol 2000).

Splice site variation

X-linked agammaglobulinemia causing g>a substitution in exon-intron boundary. Insertion of 106 nucleotides from intron leads to frameshift alteration and premature stop. Expressed protein is not detectable in Western blot (Noordzij, J. G., et al. J. Clin. Immunol. 22:306-318 2002)
