Abstract
X-linked MCT 8 mutations cause Allan-Herndon-Dudley syndrome (AHDS), characterized by severe developmental delay and specific thyroid function abnormality. The report describes a 2-y-old boy who presented with severe developmental delay, generalized hypotonia and thyroid function abnormality (high FT3, low FT4 and normal TSH) suggesting a form of impaired thyroid hormone sensitivity. Whole exome sequencing (WES) analysis revealed mutation in exon 3 of MCT 8 gene. Improvement of neurodevelopmental delay and clinical and biochemical features of thyrotoxicosis occurs with use of tri iodoacetic acid.
期刊介绍:
Indian Journal of Pediatrics (IJP), is an official publication of the Dr. K.C. Chaudhuri Foundation. The Journal, a peer-reviewed publication, is published twelve times a year on a monthly basis (January, February, March, April, May, June, July, August, September, October, November, December), and publishes clinical and basic research of all aspects of pediatrics, provided they have scientific merit and represent an important advance in knowledge. The Journal publishes original articles, review articles, case reports which provide new information, letters in relation to published articles, scientific research letters and picture of the month, announcements (meetings, courses, job advertisements); summary report of conferences and book reviews.
