Genes affected
MAGEE2 (HGNC:24935): (MAGE family member E2) This gene encodes a member of the E subfamily of MAGE (melanoma antigen-encoding gene) gene family. The gene is intronless and the encoded protein has two of the MAGE domains which are characteristic of MAGE family proteins. [provided by RefSeq, Sep 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 30, 2024The c.1015G>A (p.A339T) alteration is located in exon 1 (coding exon 1) of the MAGEE2 gene. This alteration results from a G to A substitution at nucleotide position 1015, causing the alanine (A) at amino acid position 339 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
