Abstract

Congenital bilateral laryngeal paralysis/immobilization is an uncommon condition and has been described as isolated or accompanying to some recognizable syndromes. Heterozygous mutations in the FOXP1 gene (605515) are related with intellectual disability and, language impairment with or without autistic features. Expressive language is more affected than receptive language and more than half of the patients experience oromotor dysfunction and/or feeding difficulties. Here we report a child with severe developmental, speech delay and aphonia which was considered due to bilaterally abductor vocal cord immobility. Interstitial 8700 kbp deletion encompassing FOXP1 gene was detected on 3p13p12 chromosomal region. Although it is known that FOXP1 defects are related to abnormalities in vocal communication, FOXP1-associated laryngomalacia or vocal cord paralysis/immobilization cases have not been reported yet. The FOXP1 defects are considered to be a cause of delay in speech, and it is suggested that vocal cord evaluation should be conducted in suspicious cases.
