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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2023The c.1546C>T (p.R516W) alteration is located in exon 16 (coding exon 14) of the DLG2 gene. This alteration results from a C to T substitution at nucleotide position 1546, causing the arginine (R) at amino acid position 516 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
