Goldberg-Shprintzen megacolon syndrome
is a very rare genetic condition characterized by Hirschsprung disease, megacolon, small head, widely spaced eyes, cleft palate, short stature, and learning disability. This condition has been described in about 10 individuals to date. Some of the reported cases also had iris coloboma, hypotonia, epilepsy, and ptosis. One of the described patients had sparse scalp hair, a sloping forehead, sparse eyebrows, broad nasal bridge, large ears, pointed chin, ventricular septal defect, hypospadias, syndactyly between the second and third fingers, and clubfeet. This condition appears to be inherited as an autosomal recessive trait and was found to be caused by mutations in the KIAA1279 gene.
