Genes affected

MAGEE1 (HGNC:24934): (MAGE family member E1) This gene encodes an alpha-dystrobrevin-associated MAGE (melanoma-associated antigen) protein, which is a member of the MAGE family. The protein contains a nuclear localization signal in the N-terminus, 30 12-amino acid repeats beginning at nt 60 with the consensus sequence ASEGPSTSVLPT, and two MAGE domains in the C-terminus. It may play a signaling role in brain, muscle, and peripheral nerve. This gene is located on X chromosome in a region containing loci linked to cognitive disability. [provided by RefSeq, Mar 2010]

The c.788C>A (p.T263N) alteration is located in exon 1 (coding exon 1) of the MAGEE1 gene. This alteration results from a C to A substitution at nucleotide position 788, causing the threonine (T) at amino acid position 263 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
