<unk>  is a condition caused by a mutation on the SRY-related HMG-box gene 10 (not SOX10). It was characterized in 1990, after being seen in two siblings from Yemen who presented with a "hitherto undescribed association of microcornea, colobomata of the iris and choroidea, nystagmus, severe early hearing loss, and patchy hypo- and hyperpigmentation." Some sources affirm SOX10 involvement.
