NCIt definition : Human CTAG1A wild-type allele is located in the vicinity of Xq28 and is approximately
2 kb in length. This allele, which encodes cancer/testis antigen 1 protein, may play
a role in both spermatogeneis and development of the testes. Aberrant expression of
this gene is associated with incontinentia pigmenti.;
NCIt note : Sequence analysis demonstrated that the CTAG1A gene is an identical copy of the CTAG1B
gene both are located in the vicinity of Xq28. The CTAG1A sequence lies in the opposite
orientation of and is centromeric to the CTAG1B gene. (OMIM);
