Genes affected

MAGEB4 (HGNC:6811): (MAGE family member B4) 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. The MAGEB genes are clustered on chromosome Xp22-p21. This gene sequence ends in the first intron of MAGEB1, another family member. This gene is expressed in testis. [provided by RefSeq, Jul 2008]

Ambry Genetics

Oct 29, 2021

The c.206C>T (p.T69I) alteration is located in exon 1 (coding exon 1) of the MAGEB4 gene. This alteration results from a C to T substitution at nucleotide position 206, causing the threonine (T) at amino acid position 69 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
