In two siblings suffering from congenital hypothyroidism we identified a homozygous missence mutation Ala579Val in transmembrane helix 5 of the thyrotropin receptor (TSHR) gene which motivated us to investigate molecular details of this mutation.We were interested, firstly, in the functional effects regarding signal transduction and, secondly, in the particular structural properties of the wild type receptor and the Ala579Val mutant. The aim was to gain ...
