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.770C>T (p.T257I) alteration is located in exon 2 (coding exon 2) of the SHISA6 gene. This alteration results from a C to T substitution at nucleotide position 770, causing the threonine (T) at amino acid position 257 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
