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]

The c.2423A>C (p.N808T) alteration is located in exon 23 (coding exon 22) of the DLG1 gene. This alteration results from a A to C substitution at nucleotide position 2423, causing the asparagine (N) at amino acid position 808 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
