Extremely rare. Result of a homozygous or complex heterozygous mutation of the DX11 gene on 12p11. This gene codes for a helicase essential for the replication of ' DNA and its repair, as well as for the distribution of DNA into the daughter cells during cell division.
Clinical presentation:

- microcephaly and dysmorphism: elongated face, bilateral epicanthus, broad mouth, ears in wells, narrow nostrils
- arched palate, flat philtrum and important cheeks

- cardiac malformation: VSD
- syndactyly and clinodactyly, single palmar crease
Anesthetic implications:
mental retardation, microcephaly, echocardiography
