CYP1A2 polymorphisms in slow melatonin metabolisers: a possible relationship with autism spectrum disorder?

Abstract

Of 15 patients with disappearing effectiveness of melatonin, seven were diagnosed with autism spectrum disorder, and in four of them a SNP was found. The other eight patients were known with a genetic syndrome. In six of them behaviour was considered to be autistic-type and in three of them a SNP was found. This finding may give a new direction for research into the genetic background of autism.
