Abstract

Introduction: Loss of function of the PTEN tumor suppressor gene, due to heterozygous mutation, gives rise to a wide variety of disorders, including macrocephaly/autism syndrome, PTEN hamartoma tumor syndrome, and Cowden syndrome, characterized by high risk of developing thyroid and breast cancer at young age.

Case Report: A 2-years-old male infant with simple macrocephaly was referred to the Developmental clinic due to global developmental delay, with special impairment in speech. On physical examination, he had peculiar facies, with mild and nonspecific dysmorphia, and macrocrania with dolichocephaly. There were no stigmata of neurocutaneous disease. At the age of 5 years and 6 months, the heterozygous de novo variant c.302T > C (p- lle101Thr) in PTEN gene was identified, classified as probably pathogenic. Meanwhile, the patient was diagnosed with autism spectrum disorder with moderate developmental delay.

Discussion: The morbidity and mortality of this syndrome is associated with a higher incidence of cancers, most of them curable if early detected. The correct diagnosis, allowing the establishment of an adequate surveillance program, is therefore essential.
