Allan-Herndon-Dudley syndrome (AHDS)
is an X-linked disorder caused by impaired thyroid hormone transporter. Patients with
AHDS
usually exhibit severe motor developmental delay, delayed myelination of the brain white matter, and elevated T3 levels in thyroid tests. Neurological examination of two patients with neurodevelopmental delay revealed generalized hypotonia, and not
paresis
, as the main neurological finding. Nystagmus and dyskinesia were not observed. Brain magnetic resonance imaging demonstrated delayed myelination in early childhood in both patients. Nevertheless, matured myelination was observed at 6 years of age in one patient. Although the key finding for
AHDS
is elevated free T3, one of the patients showed a normal T3 level in childhood, misleading the diagnosis of
AHDS
. Genetic analysis revealed two novel SLC16A2 mutations, p.(Gly122Val) and p.(Gly221Ser), confirming the
AHDS
diagnosis. These results indicate that
AHDS
diagnosis is sometimes challenging owing to clinical variability among patients.
