Pallister–Hall syndrome (PHS) is a rare genetic disorder that affects various body systems. [1] The main features are a non-cancerous mass on the hypothalamus (hypothalamic hamartoma) and extra digits (polydactylism). The prevalence of Pallister-Hall Syndrome is unknown; about 100 cases have been reported in publication. [2]
Polysyndactyly can be diagnosed in utero through sonographic and genetic testing, though sonography may be preferred due to the cost and risk associated with genetic testing. [19] Ultrasounds, typically done at the 14th to 16th week of pregnancy , can detect the presence of extra metacarpals , metatarsals , or phalanges .
Polydactyly also occurs in dogs, cats, and small mammals such as guinea pigs [78] and mice. [79] Cats normally have five digits on the front paws and four on the rear. Polydactyl cats have more, and this is a moderately common condition, especially in certain cat populations.
Bardet–Biedl syndrome is a pleiotropic disorder with variable expressivity and a wide range of clinical variability observed both within and between families. The most common clinical features are rod–cone dystrophy, with childhood-onset night-blindness followed by increasing visual loss; postaxial polydactyly; truncal obesity that manifests during infancy and remains problematic ...
Scalp defects-postaxial polydactyly syndrome is a very rare genetic disorder which is characterized by congenital defects of the scalp and type A postaxial polydactyly. [1] [2] An additional finding is severe intellectual disability. It is thought to be inherited in an autosomal dominant manner.
