S. Gritli et al., A novel mutation in the SLC19A2 gene in a Tunisian family with thiamine-responsive megaloblastic anaemia, diabetes and deafness syndrome, BR J HAEM, 113(2), 2001, pp. 508-513
Thiamine-responsive megaloblastic anaemia (TRMA) syndrome with. diabetes an
d deafness was found in two patients from a Tunisian kindred. The proband w
as homozygous for a novel mutation, 287delG, in the high-affinity thiamine
transporter gene, SLC19A2. We demonstrated that fibroblasts from this patie
nt exhibited defective thiamine transport. These data confirm that the SLC1
9A2 gene is the high-affinity thiamine carrier and that this novel mutation
is responsible for TRMA syndrome.
