- Prevalence
- The prevalence of Congenital Nongoitrous Hypothyroidism 6 (CHNG6) is not specifically documented in large-scale population studies. Therefore, it is considered extremely rare. Accurate prevalence data may be unavailable or difficult to ascertain due to the rarity of the condition and potential variations in reporting and diagnosis.
- Epidemiology
-
Epidemiology:
Congenital nongoitrous hypothyroidism 6 (CHNG6) is a rare genetic disorder characterized by thyroid dysgenesis, where the thyroid gland is underdeveloped or absent. This condition typically presents at birth and can lead to severe developmental and growth issues if left untreated. The exact prevalence is not well-documented due to its rarity, but congenital hypothyroidism overall occurs in approximately 1 in 2,000 to 1 in 4,000 newborns. CHNG6 is specifically caused by mutations in genes such as TSHR (Thyroid-Stimulating Hormone Receptor).
Nan:
There is no direct or specifically relevant information linking nanoscale (nan) technology or concepts directly with congenital nongoitrous hypothyroidism 6 (CHNG6), indicating no established or significant connection known at this time. - Intractability
- Congenital nongoitrous hypothyroidism 6 (CHNG6) is characterized by thyroid hormone deficiency present at birth, but it is generally not considered intractable. While it is a chronic condition requiring lifelong management, it can be effectively treated with thyroid hormone replacement therapy, allowing individuals to lead normal lives.
- Disease Severity
- For Congenital Nongoitrous Hypothyroidism 6 (CHNG6), the severity of the disease can vary. Generally, it leads to severe hypothyroidism if untreated, which can cause significant developmental delays, growth retardation, and intellectual disability. Early diagnosis and treatment with thyroid hormone replacement can mitigate many of these severe effects, allowing for normal growth and development.

- Pathophysiology
- Congenital nongoitrous hypothyroidism 6 (CHNG6) is primarily caused by mutations in the TSHR gene, which codes for the thyroid-stimulating hormone receptor. This receptor plays a crucial role in thyroid gland function, including the synthesis and release of thyroid hormones such as thyroxine (T4) and triiodothyronine (T3). Mutations in the TSHR gene lead to impaired or absent function of this receptor, resulting in reduced thyroid hormone production. Consequently, this insufficient hormone production impairs the regulation of metabolism, growth, and development from birth, manifesting as congenital hypothyroidism without goiter (enlargement of the thyroid gland).
- Carrier Status
- Carrier status for congenital non-goitrous hypothyroidism 6 (CHNG6) refers to individuals who carry one copy of the mutated gene associated with the condition but do not exhibit symptoms themselves. Being a carrier means they can potentially pass the gene mutation to their offspring.
- Mechanism
-
Congenital nongoitrous hypothyroidism 6 (CHNG6) is a rare genetic disorder affecting thyroid hormone production, evident from birth. It involves mutations in the SLC26A7 gene.
### Mechanism:
1. **Thyroid Dysfunction**: In CHNG6, the thyroid gland fails to produce enough thyroid hormones (thyroxine (T4) and triiodothyronine (T3)), which are critical for growth, metabolism, and brain development.
### Molecular Mechanisms:
1. **SLC26A7 Gene Mutation**: Mutations in the SLC26A7 gene disrupt the function of the encoded anion transporter, essential for iodine transport within the thyroid gland.
2. **Iodine Deficiency**: The disrupted anion transporter impairs iodine uptake, a crucial element in thyroid hormone synthesis.
3. **Hormone Synthesis Impairment**: Reduced iodine availability impairs the synthesis of T4 and T3. Consequently, feedback mechanisms lead to increased secretion of thyroid-stimulating hormone (TSH) from the pituitary gland, but without increasing thyroid hormone production.
4. **Clinical Manifestations**: The lack of thyroid hormones results in symptoms such as growth retardation, intellectual disability, and metabolic dysfunction if untreated.
Treatment typically involves lifelong thyroid hormone replacement therapy to manage symptoms and support normal development. - Treatment
- Congenital nongoitrous hypothyroidism 6 is a specific genetic form of congenital hypothyroidism. The primary treatment involves thyroid hormone replacement therapy, typically using levothyroxine. The goal is to normalize thyroid hormone levels and support normal growth and development. Close monitoring of thyroid function and regular follow-up with a healthcare provider are crucial in managing the condition effectively.
- Compassionate Use Treatment
