Thyroid dyshormonogenesis is a rare condition due to genetic defects in the synthesis of thyroid hormones. [1] [2]

It is due to either deficiency of thyroid enzymes, inability to concentrate, or ineffective binding.

Signs and symptoms

Patients develop hypothyroidism with a goiter.[ citation needed]

Cause

This is due to inability to produce thyroid hormones due to congenital absence of peroxidase or dehalogenase enzymes[ citation needed]

Diagnosis

Types

One particular familial form is associated with sensorineural deafness ( Pendred's syndrome).[ citation needed]

OMIM includes the following:

Type OMIM Gene
Type 1 274400 SLC5A5
Type 2A 274500 TPO
Type 2B 274600 (Pendred) SLC26A4
Type 3 274700 TG
Type 4 274800 IYD
Type 5 274900 DUOXA2
Type 6 607200 DUOX2

Treatment

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.[ citation needed]
