Hamanishi Ueba Tsuji syndrome is a rare genetic motor and sensorial neuropathy which is characterized by digital (thumb and fingers) flexion malformations, reduced touch and pain sensations of the limbs,[2] hypohidrosis, muscular dystrophy, minor physical anomalies (such as camptodactyly), and skeletal muscle atrophy,.[3] [4] [5] This disorder is inherited in an autosomal recessive fashion, and its exact prevalence is unknown, although it is believed to be around 1 in 100,000.[6] No new cases of this syndrome have been reported since 1986.[7]
