title: Cytogenetic findings of a child with transcobalamin II deficiency.
abstract: Transcobalamin II deficiency is a rare, probably autosomal recessive, inborn error of protein metabolism [Hakami et al., 1971]. Several authors have described the morphological characteristics of bone marrow aspirates from patients with this disorder; no reports have detailed the cytogenetic findings [Hitzig et al., 1974; Hakami et al., 1971; Niebrugge et al., 1982]. We report the cytogenetic findings of the bone marrow aspirates from an infant with transcobalamin II deficiency and identify fragile site expression in the hematopoietic cells in this patient.
