    A novel de novo heterozygous truncating mutation in MED12L was identified in a Chinese boy diagnosed with autism spectrum disorder.

  • 2

    The child exhibited severe autistic features and several dysmorphic traits, including a flat nasal bridge and bulbous nasal tip.

  • 3

    Magnetic resonance imaging revealed an enlarged perivascular space in the right temporal lobe of the child.

  • 4

    The case expands the phenotypic spectrum of MED12L-related cases and suggests a potential link between MED12L mutations and severe ASD.

  • 5

    Previous studies indicated that de novo mutations in MED12L may contribute to the development of autism spectrum disorder.
