Genes affected

TANC1 (HGNC:29364): (tetratricopeptide repeat, ankyrin repeat and coiled-coil containing 1) Predicted to be involved in regulation of postsynapse organization. Predicted to act upstream of or within dendritic spine maintenance; myoblast fusion; and visual learning. Predicted to be located in several cellular components, including axon terminus; neuronal cell body; and postsynaptic density. Predicted to be active in glutamatergic synapse and postsynaptic density, intracellular component. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification
