SHANK 2

The German Mental Retardation Networks (MRNET funded by the BMBF)  performs genome-wide SNP-chip analyses to determine DNA losses and gains in patients with mental retardation. Within this framework  MRMET, we have recently linked the  synaptic scaffolding protein gene SHANK2 to autism and mental retardation. We have therefore analyzed the functional impact caused by SHANK2 mutations in autistic individuals. We were able to show that the variants linked to autism spectrum disorder impair neuronal morphogenesis, synaptic transmission and behavior in mice.
