Awareness and perception of medical genetic services among Malaysian parents of autism spectrum disorders children: the lessons to be learned
Purpose Autism spectrum disorder (ASD) is a group of complex neurodevelopmental disorders with uncertain etiology. Evidence shows that genetic testing can explain about 20% of cases. This study aims to assess the level of awareness and perception of medical genetic services among Malaysian parents with ASD children. Design/methodology/approach A cross-sectional survey using an interviewer-administered questionnaire was done among 111 parents of children with ASD from August 2017 to September 2019 in two clinics in Malaysia. Findings A majority of children with ASD (80.20%) were male and diagnosed at the age of 3–4 years old (47.80%). When the autistic child was born, most mothers and fathers were aged 26–30 (40.50%) and 31–35 years old (42.30%), respectively. Another child with ASD in nuclear and extended families was reported for 11.70% and 13.50%, respectively. Only 24.30% have seen a professional genetic consultant, and 19.8% have done genetic testing for affected children. The mean score of awareness of genetic services for ASD was 2.48 ± 3.30. Having medical insurance and another child with ASD in the nuclear family was significantly associated with a higher level of awareness (p = 0.01 and p < 0.001, respectively). Most of the participants have a positive perception of these services. Originality/value Regardless of demographic factors, participants have poor awareness of genetic services for ASD, likely because the primary physician did not recommend it upon diagnosis. Increasing health-care providers’ knowledge about the current potential of genetic testing for ASD and educational campaigns for the public are critical components of using available genetic tests to improve ASD management.
