  • Specific language impairment 5 (SLI5) [MIM:615432]: A disorder characterized by a delay in early speech acquisition. It is usually associated with cerebral white matter abnormalities on brain MRI. Some individuals may show disorders in communication, consistent with autism spectrum disorder, or global developmental delay, although others ultimately show normal cognitive function. Penetrance is incomplete and expressivity is variable. {ECO:0000269 PubMed:23810381}. Note=The disease is caused by mutations affecting the gene represented in this entry.
