What is a potential barrier to genetic counseling mentioned in the text?

A significant barrier to genetic counseling is the lack of physician referrals. This issue arises because many patients may not even be aware that genetic counseling is an option or necessary for their situation unless their healthcare providers explicitly recommend it. Physicians play a crucial role in identifying patients who may benefit from genetic counseling due to family history, symptoms, or specific medical concerns. When there are insufficient referrals, individuals who could greatly benefit from genetic insights and support may remain unaware of the availability of such services, limiting access to essential information and resources that genetic counseling provides. This barrier can negatively influence the overall effectiveness of genetic counseling in improving patient outcomes related to genetic disorders.
