Genetic diagnosis and counselling at IMO Miranza Group

Dr. Esther Pomares explains what genetic diagnosis and counseling consists of.

What is genetic counseling?

Genetic analysis is performed on a blood sample, which is drawn from a patient affected by an inherited eye disease. The objective of this study is to identify the genetic alteration that triggers the pathology.

The objective of genetic analysis is to identify the alteration that causes the disease

What is an inherited disease?

Hereditary diseases usually have the following characteristics:

  • are transmitted within the same family
  • are caused by the alteration of a gene
  • can follow different patterns of inheritance

The majority of inherited eye diseases are rare and affect approximately less than 1 in 2,000 people. At IMO Miranza group, we carry out the diagnosis and genetic counseling of more than 45 hereditary diseases that affect vision.

What is genetic diagnosis for?

Genetic diagnosis allows us to:

  1. Confirm the clinical diagnosis of the pathology, since some diseases present similar symptoms and / or can be difficult to diagnose.
  2. Know how the disease will evolve, since your prognosis may vary depending on the type of genetic alteration.
  3. Inform the affected family. To do this, a genetic counseling visit is carried out that aims to identify the most probable inheritance pattern, that is, the way in which the pathology could be transmitted in the family.
  4. Alert family members who may be carriers of the disease, as they could transmit it or suffer from it in the future.
  5.  Prepare the affected patient for future gene and cell therapies.
  6.  Better understand hereditary diseases and identify new responsible genes.

Should I have a genetic test?

We recommend that you request a genetic study if you meet one of these conditions:

  1. In your family medical history there are people with hereditary or recurrent eye diseases.
  2. You have been diagnosed with an inherited eye disease.
  3. You want to have children and, in your family or in that of your partner, there are cases of hereditary eye diseases.
  4. One of your children suffers from a hereditary eye disease
