Genes affected

DLG2 (HGNC:2901): (discs large MAGUK scaffold protein 2) This gene encodes a member of the membrane-associated guanylate kinase (MAGUK) family. The encoded protein forms a heterodimer with a related family member that may interact at postsynaptic sites to form a multimeric scaffold for the clustering of receptors, ion channels, and associated signaling proteins. Multiple transcript variants encoding different isoforms have been found for this gene. Additional transcript variants have been described, but their full-length nature is not known.

The c.1444G>C (p.A482P) alteration is located in exon 15 (coding exon 13) of the DLG2 gene. This alteration results from a G to C substitution at nucleotide position 1444, causing the alanine (A) at amino acid position 482 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
