Cubilin is a high molecular weight multiligand receptor that mediates intestinal absorption of intrinsic factor-cobalamin and selective protein reabsorption in renal tubules. The genetic basis of selective intestinal cobalamin malabsorption with proteinuria was investigated in a canine model closely resembling human Imerslund-Gräsbeck syndrome caused by cubilin mutations. Canine CUBN cDNA was c...
Introduction Megaloblasc anemia is an uncommon problem in childhood most frequently associated with vitamin deficiency or gastrointesnal disease. The common causes of megaloblasc anemia are vitamin B12 (cobalamin) deficiency and folic acid deficiency. Familial selecve malabsorpon of vitamin B12 associated with proteinuria firstly was described by Imerslund (1960) and Grasbeck et al (1960) ...
The extreme rarity of pernicious anaemia in childhood has been stressed by Lambert, Prankerd, and Smellie (1961) who, by insisting on positive evidence of intrinsic factor deficiency for the diagnosis, could accept unequivocally only 7 cases in the literature but added 2 of their own, who were sibs. They may have overlooked the case described by Wilkins (1957) which was later confirmed by McInt...
A 14 year male adolescent born of 2nd degree consanguineous marriage presented with asymptomatic proteinuria and severe anemia. He had leucopenia, anisopoikilocytosis, megaloblastic erythropoiesis, megakaryocytes with low serum B12 level. His younger sibling was similarly affected. This combination suggested Imerslund-Grasbeck syndrome. The hemoglobin levels improved with injection of vitamin B...
