Genes affected

MAGI1 (HGNC:946): (membrane associated guanylate kinase, WW and PDZ domain containing 1) The protein encoded by this gene is a member of the membrane-associated guanylate kinase homologue (MAGUK) family. MAGUK proteins participate in the assembly of multiprotein complexes on the inner surface of the plasma membrane at regions of cell-cell contact. The product of this gene may play a role as scaffolding protein at cell-cell junctions. Alternatively spliced transcript variants encoding different isoforms have been identified.

The c.2409A>C (p.E803D) alteration is located in exon 14 (coding exon 14) of the MAGI1 gene. This alteration results from a A to C substitution at nucleotide position 2409, causing the glutamic acid (E) at amino acid position 803 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
