Abstract:
Recently, Butler et al. [2005; J Med Genet 42:318-321] reported the presence of heterozygous germline mutations in the PTEN tumor suppressor gene in three children with autism and macrocephaly. Here, we report the presence of PTEN mutations in two additional unrelated children with macrocephaly and autism. Our findings extend those of Butler et al. and suggest that PTEN gene sequencing should be included in the genetic evaluation of this subset of autistic individuals.
