Putative gene associated with Waardenburg syndrome type 2


WS2B is a putative gene associated with Waardenburg syndrome type 2. It has not yet been isolated from its locus of chromosome 1p21–1p13.3 since it was first reported in 1994.[1]

History[edit | edit source]

This locus was first linked to Waardenburg syndrome in 1994, when the study that first identified mutations in MITF in patients with Waardenburg syndrome type 2 also found that some patients did not have any mutations in this region.[1][2] A second 1994 study found a link to chromosome 1 in the locus 1p21–p13.3. This became known as type 2B of the condition, however it has not been documented since, and the gene responsible remains unknown.[1][3]
