Goldberg–Shprintzen syndrome

Goldberg–Shprintzen is a condition associated with mutations in KIAA1279 gene which encodes KIF-binding protein (KBP), a protein that may interact with microtubules and actin filament. KBP may play a key role in cytoskeleton formation and neurite growth.

Hirschsprung's disease may be part of the presentation. Individuals with the syndrome exhibit ocular (ptosis, hyperopia, or megalocornea), cardiac, urogenital (vesicoureteral reflux, multicystic renal dysplasia), and skeletal (oligodontia, scoliosis, high-arched palate) developmental abnormalities.
