Relevance to Autism
Snijders Blok et al., 2019 reported 19 individuals with heterozygous disruptions of the POU3F3 gene, all of whom presented with developmental delays and/or intellectual disability and impaired speech and language skills; furthermore, many individuals with POU3F3 disruptions displayed autistic features, with 7/19 individuals (37%) receiving a formal diagnosis of autism spectrum disorder (ASD).
Molecular Function
This gene encodes a POU-domain containing protein that functions as a transcription factor. The encoded protein recognizes an octamer sequence in the DNA of target genes. This protein may play a role in development of the nervous system.
