Genes affected

DLGAP1 (HGNC:2905): (DLG associated protein 1) Predicted to enable molecular adaptor activity. Predicted to be a structural constituent of postsynaptic density. Predicted to be involved in several processes, including aggresome assembly; regulation of postsynaptic neurotransmitter receptor activity; and regulation of proteasomal protein catabolic process. Predicted to be located in plasma membrane. Predicted to be part of postsynaptic density. Predicted to be active in glutamatergic synapse and postsynaptic density, intracellular component.

Nov 22, 2023

The c.518C>T (p.A173V) alteration is located in exon 4 (coding exon 1) of the DLGAP1 gene. This alteration results from a C to T substitution at nucleotide position 518, causing the alanine (A) at amino acid position 173 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
