Rare forms of diabetes

The common forms of diabetes are type 1, type2 and gestational diabetes. Apart from these we have some rare forms of diabetes. They are:

  1. Maturity onset diabetes of the young (MODY)
  2. Wolfram syndrome
  3. Alstrom syndrome
  4. Neonatal diabetes
  5. Latent autoimmune diabetes in adults (LADA)

Maturity onset diabetes of the young. (MODY)

MODY is a genetic diabetes and it usually run in families. It occurs due to mutation. Mutation causes a change in in the genetic makeup. Gene alteration in parents can produce a 50 percent chance of causing the same disease in the children as it is inherited. If this mutation is inherited the child will surely develop MODY, independent of the race, lifestyle and other patterns.

Wolfram syndrome

Wolfram syndrome is also known as DIDMOAD syndrome of diabetes, due to the features associated with this – (diabetes insipidus + diabetes mellitus + optic atrophy + deafness). It is a rare genetic disorder.

Alstrom syndrome

Alstrom syndrome is a rarest of the rare inherited syndrome that has features similar to type 2 diabetes mellitus. It occurs due to mutation in ALMS1 gene. It is an autosomal recessive genetic disorder.

Neonatal diabetes

Neonatal diabetes is type of diabetes mellitus that affect the neonates that is, young infants below 6 months of age. Here, the ability to produce insulin is disturbed and so glucose accumulate in the body. It is controlled by single gene (monogenic). This very rare disease occur one in five lakh births. It is different from type 1 diabetes.

Latent autoimmune diabetes in adults (LADA)

It is a slowly progressing hereditary autoimmune type of diabetes. It occurs due to the blockage of insulin production by the pancreas. It is also known as type 1.5 diabetes as it is type 1 diabetes that is having close similarity with type 2 diabetes.
