Genes affected

SHISA6 (HGNC:34491): (shisa family member 6) Predicted to enable ionotropic glutamate receptor binding activity. Predicted to be involved in several processes, including excitatory chemical synaptic transmission; regulation of short-term neuronal synaptic plasticity; and regulation of signal transduction. Predicted to be located in asymmetric, glutamatergic, excitatory synapse. Predicted to be part of AMPA glutamate receptor complex. Predicted to be active in glutamatergic synapse; postsynaptic density; and synaptic membrane. Predicted to be integral component of postsynaptic density membrane.

The c.143G>T (p.G48V) alteration is located in exon 1 (coding exon 1) of the SHISA6 gene. This alteration results from a G to T substitution at nucleotide position 143, causing the glycine (G) at amino acid position 48 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
