Ritscher-Schinzel syndrome

Dr Yair Glick and Dr Daniel J Bell et al.

Ritscher-Schinzel syndrome (RTSC), also known as 3C (cranio-cerebello-cardiac) syndrome, is a rare entity with a variable spectrum of CNS (primarily cerebellar), craniofacial, and congenital heart defects.

Ritscher-Schinzel syndrome is divided into two types, RTSC1 and RTSC2, according to which genes are involved:

  • RTSC1 is caused by a mutation in the KIAA0196 gene on chromosome 8q24 3. It is transmitted in an autosomal recessive pattern of inheritance
  • RTSC2 is caused by a mutation in the CCDC22 gene on chromosome Xp11 4. It is transmitted in an X-linked recessive pattern of inheritance
