NIH Rare Diseases : ⁵⁴ Pallister-Hall syndrome (PHS) is a genetic disease that affects the development of many parts of the body. Common features include extra fingers and/or toes (polydactyly), extra skin between the fingers or toes (syndactyly), an abnormal growth in the brain called a hypothalamic hamartoma, and a malformation of the airway known as bifid epiglottis. The bifid epiglottis in rare cases may lead to respiratory failure. While the hypothalamic hamartoma in most cases does not cause problems, in some cases it may cause neurological problems such as seizures, growth hormone deficiency, precocious puberty, or a deficiency of many hormones (panhypopituitarism) that can result in cortisol deficiency. Other symptoms of PHS may include imperforate anus, abnormalities in the kidneys, heart defects, small genitalia, lack of fingers, nail problems, cleft palate, bifid uvula, and development delay and behavioral problems.  Pallister-Hall syndrome is caused by mutations in the GLI3 gene. Inheritance is autosomal dominant, however, in about a quarter of cases Pallister-Hall syndrome results from a new (de novo) mutation. The diagnosis of Pallister-Hall syndrome can be made when there is a hypothalamic hamartoma and polydactyly. The genetic test that identifies a mutation in the GLI3 gene confirms the diagnosis. Treatment is based on the symptoms, and may include medication for the early treatment of cortisol deficiency and seizures, surgery for imperforate anus and/or polydactyly, and special education when developmental delays are present. The prognosis depends on which symptoms are present and their severity.

MalaCards based summary : Pallister-Hall Syndrome, also known as phs, is related to culler-jones syndrome and mckusick-kaufman syndrome. An important gene associated with Pallister-Hall Syndrome is GLI3 (GLI Family Zinc Finger 3), and among its related pathways/superpathways are Hedgehog signaling pathway and Pathways in cancer. Affiliated tissues include pituitary, brain and skin, and related phenotypes are hypothalamic hamartoma and macrocephaly

Genetics Home Reference : ²⁶ Pallister-Hall syndrome is a disorder that affects the development of many parts of the body. Most people with this condition have extra fingers and/or toes (polydactyly), and the skin between some fingers or toes may be fused (cutaneous syndactyly). An abnormal growth in the brain called a hypothalamic hamartoma is characteristic of this disorder. In many cases, these growths do not cause any health problems; however, some hypothalamic hamartomas lead to seizures or hormone abnormalities that can be life-threatening in infancy. Other features of Pallister-Hall syndrome include a malformation of the airway called a bifid epiglottis, an obstruction of the anal opening (imperforate anus), and kidney abnormalities. Although the signs and symptoms of this disorder vary from mild to severe, only a small percentage of affected people have serious complications.

OMIM : ⁵⁸ Pallister-Hall syndrome is a pleiotropic autosomal dominant disorder comprising hypothalamic hamartoma, pituitary dysfunction, central polydactyly, and visceral malformations (Biesecker et al., 1996). (146510)

UniProtKB/Swiss-Prot : ⁷⁶ Pallister-Hall syndrome: An autosomal dominant disorder characterized by a wide range of clinical manifestations. Clinical features include hypothalamic hamartoma, pituitary dysfunction, central or postaxial polydactyly, and syndactyly. Malformations are frequent in the viscera, e.g. anal atresia, bifid uvula, congenital heart malformations, pulmonary or renal dysplasia.
