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]

Uncertain significance, criteria provided, single submitterclinical testingGeneDxFeb 08, 2022In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge; Variants in candidate genes are classified as variants of uncertain significance in accordance with ACMG guidelines (Richards et al., 2015) -
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 05, 2022This sequence change replaces proline, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 711 of the MAGI2 protein (p.Pro711Thr). This variant is present in population databases (rs144078604, gnomAD 0.06%). This variant has not been reported in the literature in individuals affected with MAGI2-related conditions. ClinVar contains an entry for this variant (Variation ID: 129551). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 06, 2021The c.2131C>A (p.P711T) alteration is located in exon 12 (coding exon 12) of the MAGI2 gene. This alteration results from a C to A substitution at nucleotide position 2131, causing the proline (P) at amino acid position 711 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
