Counsel a family on a new fragile X diagnosis and cascade testing — OSCE
OSCE communication and shared decision-making station: explaining to parents what a new fragile X syndrome diagnosis means for their three-year-old son, why a normal microarray did not detect it, what FMR1 testing involves, what the supportive management looks like, why cascade testing of the wider family matters, and what the mother's premutation carrier status means for her health and future pregnancies — while addressing guilt, the search for a cure, and the temptation to defer family testing.

Task
Counsel the parents. You have five minutes. Demonstrate an organised, empathic, and accurate explanation that addresses the four questions a fellowship communication station rewards: what the diagnosis means and why the earlier test missed it, what the plan is for their son, what the mother's premutation carrier status means for her, and what cascade testing of the wider family involves. The management and counselling framework follows the AAP health supervision guideline. [1]
