Research paper thumbnail of New recessive syndrome of microcephaly, cerebellar hypoplasia, and congenital heart conduction defect

They also shared distinct facial features and similar appearance of their hands and feet. Childhood-onset insulindependent diabetes mellitus developed in one affected child around the age of 9 years. Molecular analysis excluded mutations in potentially related genes such as PTF1A, EIF2AK3, EOMES, and WDR62. This condition appears to be unique of other known conditions, suggesting a unique clinical entity of autosomal recessive mode of inheritance.
