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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 12, 2024The c.2681G>A (p.R894Q) alteration is located in exon 16 (coding exon 16) of the MAGI1 gene. This alteration results from a G to A substitution at nucleotide position 2681, causing the arginine (R) at amino acid position 894 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
