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]

MAGEE2 Gene-Disease associations (from GenCC):

• male infertility with azoospermia or oligozoospermia due to single gene mutation

  Inheritance: XL Classification: MODERATE Submitted by: King Faisal Specialist Hospital and Research Center

LOC107985664 (HGNC:):

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.09913179).
