Neurological involvement in hereditary transcobalamin II deficiency.
A case of hereditary transcobalamin II deficiency with neurological involvement is described. The patient presented in early infancy with megaloblastic anaemia and was treated with folinic acid from 6 weeks of age. The diagnosis of transcobalamin II deficiency was not made until he was 2 years old when he showed severely retarded intellectual development, ataxia and pyramidal deficit in the lim...
متن کاملTranscobalamin II Deficiency in Four Cases with Novel Mutations
OBJECTIVE Transcobalamin II deficiency is one of the rare causes of inherited vitamin B12 disorders in which the patients have characteristically normal or high vitamin B12 levels related to the transport defect of vitamin B12 into the cell, ending up with intracellular cobalamin depletion and high homocysteine and methylmalonic acid levels. MATERIALS AND METHODS Herein, we describe the findi...

A case of transcobalamin II (TCII) deficiency in which a total absence of TCII was demonstrated both functionally and immunologically is reported. Unlike previously described patients, this child has been maintained on oral hydroxocobalamin, 2 mg daily, without any parenteral supplementation for the last five years. At the age of six years her development is normal and her health is good. Plasm...
متن کاملSPAK Deficiency Corrects Pseudohypoaldosteronism II Caused by WNK4 Mutation
Stimulation of the OSR1 (Oxidative stress-responsive kinase-1)/SPAK [STE20 (sterile 20)/SPS1-related proline/alanine-rich kinase]-NCC (Na(+)-Cl(-) cotransporter) signaling cascade plays an important role in the WNK [With-No-Lysine (K)] kinase 4 D561A knock-in mouse model of pseudohypoaldosteronism type II (PHA II) characterized by salt-sensitive hypertension and hyperkalemia. The aim of this st...
متن کاملCongenital Transcobalamin II Deficiency Presenting Atypically With a Low Serum Cobalamin Level: Studies Demonstrating the Coexistence of a Circulating Transcobalamin
A case of transcobalamin II deficiency with several unique features is described. The clinical presentation was typical. except for a slightly delayed age at presentation and the occurrence of apparent neurologic dysfunction from the beginning. The unusual biochemical feature was a low serum cobalamin level (97 pg/mI). Several cobalaminbinding protein abnormalities coexisted and antedated cobal...
