Cancer/Testis Antigen Family 47, Member B1 (CT47B1)

Chen et al. (2006) identified 13 tandem copies of the CT47 gene, including CT47B1, on chromosome Xq24.Using an accession number provided by Strausberg et al. (2002) and assigned to CT47A11, , Hartz (2009) identified 12 copies of the CT47 gene on chromosome Xq24 (build 36.1). Of these copies, 9 share 100% nucleotide identity, and 3 share over 90.0% nucleotide identity. All contain 3 exons.Hartz (2009) mapped the duplications of the CT47 gene to chromosome Xq24 based on alignment of a sequence containing CT47A11 with the genomic sequence (build 36.1).The copies are numbered from the most telomeric copy CT47.1 (CT47A1) through the most centromeric copy CT47.13 (CT47B1).
