Diffusion of information about neurofibromatosis type 1 DNA testing

Area of Science:

• Medical Genetics
• Patient Communication
• Genetic Disorder Management

Background:

• Limited data exists on how individuals with genetic disorders learn about DNA testing availability.
• Understanding information dissemination is crucial for assessing genetic test utilization.

Purpose of the Study:

• To survey healthcare centers for individuals with neurofibromatosis type 1 (NF 1) to understand DNA test information dissemination.
• To identify how patients with NF 1 are informed about genetic testing options.

Main Methods:

• A survey was conducted among NF 1 care centers two years after a newsletter announced familial NF 1 testing availability.
• The survey assessed whether centers notified their patients about the DNA test and the methods used for notification.

Main Results:

• 65% of responding centers attempted to notify patients of DNA test availability.
• Most notifications occurred individually in clinic (80%), with others using phone or mail.
• A significant 35% of NF centers did not inform patients about available DNA testing.

Conclusions:

• Factors beyond awareness of DNA test availability influence its utilization in NF 1.
• Disparities exist in how NF centers disseminate genetic testing information.
• Proactive patient notification by healthcare providers is not consistently practiced for NF 1 DNA testing.
