Genes affected

MAGI2 (HGNC:18957): (membrane associated guanylate kinase, WW and PDZ domain containing 2) The protein encoded by this gene interacts with atrophin-1. Atrophin-1 contains a polyglutamine repeat, expansion of which is responsible for dentatorubral and pallidoluysian atrophy. This encoded protein is characterized by two WW domains, a guanylate kinase-like domain, and multiple PDZ domains. It has structural similarity to the membrane-associated guanylate kinase homologue (MAGUK) family. [provided by RefSeq, Jul 2008]

Collection Method:clinical testing

The c.4357G>A (p.A1453T) alteration is located in exon 22 (coding exon 22) of the MAGI2 gene. This alteration results from a G to A substitution at nucleotide position 4357, causing the alanine (A) at amino acid position 1453 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
