Genes affected

MAGEB6 (HGNC:23796): (MAGE family member B6) This gene is a member of the MAGEB gene family. The members of this family have their entire coding sequences located in the last exon, and the encoded proteins show 50 to 68% sequence identity to each other. The promoters and first exons of the MAGEB genes show considerable variability, suggesting that the existence of this gene family enables the same function to be expressed under different transcriptional controls. This gene is expressed in testis, and in a significant fraction of tumors of various histological types. The MAGEB genes are clustered on chromosome Xp22-p21. [provided by RefSeq, Jul 2008]

Ambry Genetics

Mar 19, 2024

The c.775G>A (p.G259S) alteration is located in exon 2 (coding exon 1) of the MAGEB6 gene. This alteration results from a G to A substitution at nucleotide position 775, causing the glycine (G) at amino acid position 259 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
