Genes affected

MAGEA8 (HGNC:6806): (MAGE family member A8) This gene is a member of the MAGEA gene family. The members of this family encode proteins with 50 to 80% sequence identity to each other. The promoters and first exons of the MAGEA genes show considerable variability, suggesting that the existence of this gene family enables the same function to be expressed under different transcriptional controls. The MAGEA genes are clustered at chromosomal location Xq28. They have been implicated in some hereditary disorders, such as dyskeratosis congenita. Multiple alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Oct 2009]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.200G>A (p.G67D) alteration is located in exon 4 (coding exon 1) of the MAGEA8 gene. This alteration results from a G to A substitution at nucleotide position 200, causing the glycine (G) at amino acid position 67 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
