ITGA10 encodes the α10 subunit of the α10β1 integrin complex and is located within the recurrent 1q21.1 microdeletion region associated with thrombocytopenia-absent radius syndrome. Immunoblotting studies demonstrated mildly reduced ITGA10 expression, an additional ∼80 kDa ITGA10-related band, markedly reduced ITGB1 expression, and absence of β-actin expression in platelet lysates despite wild-type ACTB and ITGB1 genotypes.
