Living with Neonatal diabetes mellitus with congenital hypothyroidism

A rare genetic condition with diabetes and an underactive thyroid from birth, and sometimes eye, liver, and kidney problems.

Understanding Neonatal diabetes mellitus with congenital hypothyroidism

Neonatal diabetes mellitus with congenital hypothyroidism is a rare genetic condition with slow growth before birth, diabetes, and an underactive thyroid.

Babies have permanent diabetes from the newborn period and an underactive thyroid from birth. Other features can include glaucoma from birth, liver disease, kidney cysts, trouble with pancreas digestive function, hearing loss, developmental delay, and mild facial differences.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Diabetes starting in the newborn period
  • Underactive thyroid from birth
  • Slow growth before birth
  • High eye pressure (glaucoma)
  • Liver scarring (hepatic fibrosis)
  • Kidney cysts

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include genetic specialists and kidney specialists.

  3. Consider genetic testing

    Changes in GLIS3 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
