Genes affected

MAGEA6 (HGNC:6804): (MAGE family member A6) 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. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2013]

The c.850G>A (p.V284M) alteration is located in exon 3 (coding exon 1) of the MAGEA6 gene. This alteration results from a G to A substitution at nucleotide position 850, causing the valine (V) at amino acid position 284 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
