Abstract:
We describe a novel de novo heterozygous variant in SYNGAP1 (c.1741C>T, p.R581W), identified through targeted resequencing in an 8-year-old boy with intellectual disability, autism spectrum disorder, distinctive dysmorphic features, and no seizures. Our data strongly suggest that the SYNGAP1 variant is causative of intellectual disability in this patient.
