Congenital arhinia with de novo reciprocal translocation, t(3;12)(q13.2;p11.2).

A female newborn suffering from congenital arhinia with complete airway obstruction is reported. In addition, she had hypertelorism, microphthalmia, high-arched palate, and hypoplasia of the auditory canal and mastoid and facial bones, along with the absence of olfactory bulbs and tracts. She had a de novo reciprocal translocation between chromosomes 3q13.2 and 12p11.2. Certain gene(s) located at either of the breakpoints, 3q13.2 and 12p11.2, may be involved in the pathogenesis of her arhinia.
