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.

DLG2 Gene-Disease associations (from GenCC):

• delayed puberty, self-limited

  Inheritance: AD, AR Classification: LIMITED Submitted by: Ambry Genetics
• neurodevelopmental disorder

  Inheritance: AD Classification: LIMITED Submitted by: Ambry Genetics

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.59).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.954 is higher than 0.05.
