Genes affected

DLGAP4 (HGNC:24476): (DLG associated protein 4) The product of this gene is a membrane-associated guanylate kinase found at the postsynaptic density in neuronal cells. It is a signaling molecule that can interact with potassium channels and receptors, as well as other signaling molecules. The protein encoded by this gene can interact with PSD-95 through its guanylate kinase domain and may be involved in clustering PSD-95 in the postsynaptic density region. The encoded protein is one of at least four similar proteins that have been found. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

The c.86G>A (p.R29H) alteration is located in exon 2 (coding exon 1) of the DLGAP4 gene. This alteration results from a G to A substitution at nucleotide position 86, causing the arginine (R) at amino acid position 29 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
