Thyrotoxicosis in MCT8 deficiency.

The Journal of clinical endocrinology and metabolism2026 Mar 17

Monocarboxylate transporter 8 (MCT8) deficiency, also known as Allan-Herndon-Dudley syndrome, is a rare, severely debilitating, and life-limiting genetic disorder caused by variants in the SLC16A2 gene that render the MCT8 thyroid hormone transporter partially or completely dysfunctional. MCT8 is highly expressed throughout the body, including the brain. Its deficiency disrupts thyroid hormone homeostasis and is associated with 2 distinct concomitant clinical presentations: persistent peripheral thyrotoxicosis resulting from elevated serum levels of triiodothyronine and neurodevelopmental impairment arising from low thyroid hormone levels in the brain. The disorder severely impacts quality of life and reduces life expectancy to a median of 35 years due to a range of clinical sequelae, with approximately 30% of affected individuals dying during childhood. Recognition and treatment of thyrotoxicosis are crucial to prevent associated symptoms and long-term sequelae.

Altered Dopamine Metabolism and Response to Treatment with Levodopa/Carbidopa in MCT8 Deficiency.

Movement disorders : official journal of the Movement Disorder Society2026 Feb

Allan-Herndon-Dudley syndrome (AHDS)/monocarboxylate transporter 8 (MCT8) deficiency is a rare X-linked encephalopathy caused by SLC16A2 variants, impairing thyroid hormone (TH) transport into the brain. This leads to early central nervous system (CNS) TH deficiency, affecting brain maturation. Dopaminergic circuit involvement is suggested by both pathophysiology and clinical features, reminiscent of infantile parkinsonism. This study investigates dopamine metabolism and levodopa/carbidopa response in MCT8 patients. We retrospectively and prospectively collected clinical, genetic, and neuroimaging data, performed cerebrospinal fluid (CSF) biogenic amine analyses, and conducted neurological assessments before and after the levodopa trial (10 mg/kg/day). Ten patients exhibited developmental delay, spasticity, and infantile parkinsonism. CSF analysis showed reduced homovanillic acid in 3/10 patients, with 7/10 in the lowest quartile. Levodopa improved parkinsonism and reactivity in 7/10 patients. Our findings confirm dopaminergic involvement in AHDS and show that levodopa/carbidopa effectively treats extrapyramidal symptoms. Further investigations could differentiate presynaptic and postsynaptic defects to optimize dopaminergic therapy. © 2025 The Author(s).

Novel MCT8 mutation: diagnostic value of T3/T4 ratio.

Journal of pediatric endocrinology &amp; metabolism : JPEM2026 Jan 23

To highlight the diagnostic value of the T3/T4 ratio in Allan-Herndon-Dudley syndrome (AHDS) through a case report of a novel SLC16A2 mutation. We report a 36-month-old boy with severe neurodevelopmental delay and axial hypotonia. Initial thyroid function tests at 10 months showed TSH at 4.77 μIU/mL and T3 at 8.9 pmol/L. Brain MRI was normal. At 28 months, genetic analysis identified a novel hemizygous c.1343_1344dup mutation in the SLC16A2 gene. Follow-up thyroid profiling at 36 months revealed the characteristic AHDS pattern: elevated free T3 (10.20 pmol/L), low free T4 (7.80 pmol/L), and borderline high TSH (5.20 μIU/mL), with a T3/T4 ratio of 1.31 pmol/pmol. This case highlights the diagnostic value of the T3/T4 ratio (>0.75 pmol/pmol) as an essential biochemical marker of AHDS in any male infant presenting with unexplained developmental delay and hypotonia. A systematic diagnostic approach including early T3 measurement and T3/T4 ratio calculation should be applied in the initial evaluation of severe developmental delays, even in the presence of normal brain MRI findings, to avoid diagnostic delays in AHDS.

Structural insights into brain thyroid hormone transport via MCT8 and OATP1C1.

Cell2025 Oct 02

Adequate delivery of thyroid hormones to the brain is crucial for normal neurological development. MCT8 and OATP1C1, two solute carrier (SLC) transporters, mediate the passage of thyroid hormones across the blood-brain barrier and into the central nervous system. Mutations in MCT8 result in Allan-Herndon-Dudley syndrome (AHDS), an X-linked birth defect characterized by neurodevelopmental impairments and peripheral hyperthyroidism, whereas OATP1C1 deficiency is linked to brain hypometabolism and progressive neurodegeneration. Here, we report cryoelectron microscopy (cryo-EM) structures of MCT8 and OATP1C1 bound with the active thyroid hormone triiodothyronine (T3) and the prohormone thyroxine (T4) at 2.9 and 2.3 Å resolutions, respectively. Combined with functional studies, we elucidate their distinct thyroid hormone recognition and transport mechanisms and explain disease mutations. Although extracellular allosteric sites are not a common feature of SLC transporters, we identify one in OATP1C1. Collectively, these findings illuminate key aspects of thyroid hormone transport, a fundamental process in development and disease.

A novel TIMM8A mutation in Mohr-Tranebjaerg syndrome without hearing loss and with basal ganglia iron deposition.

Orphanet journal of rare diseases2025 Jul 01

Mohr-Tranebjaerg syndrome (MTS) is a rare X-linked recessive neurodegenerative disorder caused by pathogenic variants in the TIMM8A gene. TIMM8A, also known as Deafness-Dystonia Peptide-1 (DDP1) is a mitochondrial intermembrane space protein involved in the import and insertion of hydrophobic membrane proteins from the cytoplasm into the mitochondrial inner membrane. MTS typically presents early-onset progressive hearing loss, dystonia, visual impairment, and cognitive decline. Here, we report a case of a male adolescent with a previously undescribed variant in TIMM8A, associated with progressive dystonia but no hearing loss, highlighting the clinical variability of MTS. A 16-year-old male was referred for genetic evaluation due to a 6-year history of progressive dystonia, motor coordination difficulties, and iron deposits in the basal ganglia detected by brain MRI. Family history revealed mild motor abnormalities in his maternal uncle and recurrent muscle spasms in his mother. Whole-exome sequencing (WES) identified a c.98_101dupAGCA variant in TIMM8A in hemizygosity, classified as likely pathogenic. This variant causes a frameshift leading to a truncated protein. The patient inherited the variant from his mother, who is heterozygous for the mutation. Although the patient lacks the characteristic early-onset hearing loss seen in MTS, his neurological presentation and the imaging findings are consistent with the syndrome. This case underscores the phenotypic heterogeneity of Mohr-Tranebjaerg syndrome, where patients may present with prominent neurological symptoms such as dystonia without the hallmark auditory dysfunction. The identification of a novel TIMM8A variant expands the mutational spectrum of this rare disorder and provides insights into genotype-phenotype correlations. The absence of hearing loss in this patient raises important questions about the variability in the expression of the mutated TIMM8A. This report highlights a novel TIMM8A mutation associated with Mohr-Tranebjaerg syndrome, presenting primarily with dystonia and iron accumulation in the basal ganglia. The findings contribute to the understanding of the clinical spectrum of MTS and emphasize the importance of genetic testing in patients with unexplained progressive neurological symptoms.
