Thyroid dyshormonogenesis is a rare condition due to genetic defects in the synthesis of thyroid hormones. It is due to either deficiency of thyroid enzymes, inability to concentrate, or ineffective binding. See more Patients develop hypothyroidism with a goiter. See more This is due to inability to produce thyroid hormones due to congenital absence of peroxidase or dehalogenase enzymes See more These patients respond well to levothyroxine (synthetic T4) and the goiter may decrease in size if any. They may not require surgery at any time. See more WebThyroid dysgenesis occurs mostly as a sporadic disease. However, a small but significant proportion of the cases are due to defects in transcription factors.
