coloboma of macula-brachydactyly type B syndrome
MONDO:0007353
Coloboma of macula - brachydactyly type B or Sorsby syndrome is a malformation syndrome characterized by the combination of bilateral coloboma of macula with horizontal pendular nystagmus and severe visual loss, and brachydactyly type B. The hand and feet defects comprise shortening of the middle and terminal phalanges of the second to fifth digits, hypoplastic or absent nails (congenital anonychia), broad or bifid thumbs and halluces, syndactyly and flexion deformities of the joints of some digits. Coloboma of macula - brachydactyly type B is inherited in a dominant manner.
