The third patient with Tsukahara-Azuno-Kaiji syndrome with type A1 brachydactyly, dwarfism, microcephaly, scoliosis, intellectual disability, ptosis, and hearing loss

We report the case of the third patient with Tsukahara-Azuno-Kaiji syndrome. It is characterized by brachydactyly A1, dwarfism, microcephaly, scoliosis, intellectual disability, ptosis, and hearing loss. The first patient was reported in 1989, and the second in 2010. The present patient had many features in common with the previous 2 patients, with a few minor differences. Although this combination of symptoms is very characteristic, the clinicians should know about this syndrome to diagnose it. The syndrome in this patient appeared sporadically, and chromosome G-banding revealed a normal female karyotype of 46XX. However, further genetic research could not be performed. Steady accumulation of information will enable us to discover the true clinical and genetic nature of the disease and to make the diagnosis more easily.
