Bardet-Biedl syndrome (BBS) is an inherited condition that affects many parts of the body. People with this syndrome have progressive visual impairment due to cone-rod dystrophy; extra fingers or toes (polydactyly); truncal obesity; decreased function of the male gonads (hypogonadism); kidney abnormalities; and learning difficulties. Mutations in many genes are known to cause Bardet-Biedl syndrome and inheritance is usually autosomal recessive. Treatment depends on the symptoms present in each person.
