Description : Meckel syndrome, also known as Meckel-Gruber syndrome, is a severe pleiotropic autosomal
recessive developmental disorder caused by dysfunction of primary cilia during early
embryogenesis. There is extensive clinical variability and controversy as to the minimum
diagnostic criteria. Early reports, including that of Opitz and Howe, 1969) and Wright
et al. (1994), stated that the classic triad of Meckel syndrome comprises (1) cystic
renal disease; (2) a central nervous system malformation, most commonly occipital
encephalocele; and (3) polydactyly, most often postaxial. However, based on a study
of 67 patients, Salonen (1984) concluded that the minimum diagnostic criteria are
(1) cystic renal disease; (2) CNS malformation, and (3) hepatic abnormalities, including
portal fibrosis or ductal proliferation. In a review of Meckel syndrome, Logan et
al. (2011) stated that the classic triad first described by Meckel (1822) included
occipital encephalocele, cystic kidneys, and fibrotic changes to the liver. - Genetic
