Genetic counseling in autism and pervasive developmental disorders.

Fraley (1998) wrote a how-to guide for genetic counselors who meet families with autism. The paper spells out what to say about the chance autism will show up again in brothers or sisters.

It tells counselors to team up with autism doctors so families get clear facts and warm support at the same time.

The paper does not give new numbers. Instead it gives a road map: talk about recurrence risk, explain the broader autism phenotype, and let parents ask every question they have.

The goal is to help families make informed choices about future children without scaring or confusing them.

Ohashi et al. (2021) updates the story. They tested modern gene panels in kids with non-syndromic autism and found only one in ten cases got a clear answer. Counselors using the 1998 script should now add: "Most test results come back fuzzy."

Ayhan et al. (2021) adds real-world uptake data. In their survey, only a third of families accepted free post-diagnosis genetic testing unless the doctor pushed hard. The 1998 protocol assumed families would want testing; the 2021 data shows you must sell the idea.

Meuret et al. (2001) extends the same risk estimates to children who also have profound intellectual disability. Recurrence odds stay the same, so counselors can keep using the 1998 numbers for this subgroup.

When you sit with parents, pair the 1998 talking points with the newer facts. Tell them most genetic tests give cloudy results and that many families skip testing unless you explain the payoff. This keeps expectations real and saves later disappointment.
