Genes affected

DLG1 (HGNC:2900): (discs large MAGUK scaffold protein 1) This gene encodes a multi-domain scaffolding protein that is required for normal development. This protein may have a role in septate junction formation, signal transduction, cell proliferation, synaptogenesis and lymphocyte activation. A multitude of transcript variants deriving from alternative splicing and the use of multiple alternate promoter have been observed, including some splice variants that may be specific to brain and other tissues. An upstream uORF may regulate translation at some splice variants of this gene. [provided by RefSeq, Sep 2018]

DLG1 Gene-Disease associations (from GenCC):

• Brugada syndrome

  Inheritance: Unknown Classification: LIMITED Submitted by: Genomics England PanelApp

ACMG classification

Our verdict: Benign. The variant received -8 ACMG points.

• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.687 is higher than 0.05.
