What happens if cousins have a baby?

In 2023 Resto NYC had an article about cousin couples:

When cousins have a child together, there are some elevated risks of genetic problems and birth defects. However, risks are still low in most cases, around 4-7% for first cousins. Major disabilities are very rare unless cousin marriage has occurred for multiple generations. The bigger challenges tend to be the social disapproval and stigma. Cousin couples planning children need to get genetic counseling, understand laws, and prepare emotionally. Overall, cousins can safely have healthy children together in most instances, as long as they are aware of the small risks and challenges involved.
