Evidence for a Pathogenic Role of CSMD1 in Childhood Apraxia of Speech

Abstract

Childhood apraxia of speech (CAS) is a pediatric motor speech disorder. The genetic etiology of this complex neurological condition is not yet well understood, although some genes have been linked to it. We describe the case of a boy with a severe and persistent motor speech disorder, consistent with CAS, and a coexisting language impairment.

Whole exome sequencing in our case revealed a de novo and splicing mutation in the CSMD1 gene.

Keywords
