BackgroundThis communication examines the expanding phenotypes of the MECP2 C-terminal atypical Rett syndromes in males and their affected carrier mothers.DescriptionsWe describe three males with normal karyotypes who presented with congenital evolving complex neurodevelopmental encephalopathies with multifaceted symptomatology of hypotonia, epilepsy, ataxia, spasticity, movement disorders, behavioral issues, severe intellectual impairment, and communication skills, and a protracted regression phase followed by stabilization. These phenotypes did not prompt us to identify atypical Rett syndrome early in childhood.ResultsGenetic analysis identified the two brothers with C-terminal truncation and the third male with C-terminal missense mutations. These mutations were inherited from their mothers, both of whom had incompletely characterized modest intellectual, mental health, social, and gastrointestinal impairments. Neither was independently able to care properly for their son(s).ConclusionsMutations of the MECP2 gene should be considered early in males with hypotonia, developmental delay, profound intellectual impairment, and seizures, associated with a mother with psychosocial, cognitive, and gastrointestinal impairments. Counseling and supporting mildly affected mothers requires both medical and social efforts.
