For Waardenburg syndrome, type 2D, PMID: 30561083 Only 2 cases reported that resulted from homozygous SNAI2 deletions. Both had sensorineural hearing loss and heterochromia, without any cutaneous or dysmorphic manifestations. Since the initial publication in 2002, no additional confirmatory cases have been reported.
