Fragile X Syndrome Infant. This study examined the developmental profile of male infants with fragile X syndrome FXS and its divergence from typical development and development of infants at high risk for autism associated with familial recurrence ASIBs. However there are no published data on brain development in children with FXS during infancy. What is fragile X syndrome. Humans with FXS exhibit increased anxiety sensory hypersensitivity seizures repetitive behaviors cognitive inflexibility and social behavioral impairments.
About a third of those affected have features of autism such as problems. Fragile X syndrome FXS is the most common single gene cause of autism and intellectual disabilities. Participants included 174 boys ranging in age from 5 to 28 months. FXS is the most common inherited cause of intellectual disability and is caused by a mutation in the Fragile X Mental Retardation 1 FMR1 gene located on the X chromosome. The syndrome occurs in approximately 1 in 3600 males and 1 in 4000-6000 females. Newborn screening is one approach used for early identification of infants with other conditions.
However there are no published data on brain development in children with FXS during infancy.
Fragile X syndrome FXS is one of the most common causes of inherited intellectual disability. Fragile X syndrome is characterized by developmental problems including intellectual disability and delayed speech and language development. When these children start to go through puberty however many will begin to develop certain features that are typical of those with Fragile X. Fragile X syndrome FXS is a genetic disorder characterized by mild-to-moderate intellectual disability. Fragile X syndrome FXS is the most common single gene cause of autism and intellectual disabilities. Babies with fragile X syndrome spend more time looking at a toy before switching their attention elsewhere than do healthy controls according to a study published 1 July in the Journal of Autism and Developmental Disorders 1.
