Clinical Information
  • A genetic syndrome caused by abnormalities in chromosome 11. It is characterized by large birth weight, macroglossia, umbilical hernia, ear abnormalities, and hypoglycemia. Patients with this syndrome have an increased risk of developing embryonal tumors (gonadoblastoma, hepatoblastoma, wilms tumor, rhabdomyosarcoma) and adrenal cortex carcinomas.
  • A rare genetic syndrome caused by mutations in the nsd1 gene. It is characterized by excessive physical growth early in life, mild mental retardation, and delayed cognitive and social development. Children affected by this syndrome are tall with larger than normal heads.
  • A rare, overgrowth disorder in which babies are large at birth and may develop low blood sugar. Other common symptoms are a large tongue, large internal organs, and defects of the abdominal wall near the navel. Beckwith-wiedemann syndrome increases the risk of developing certain cancers, especially wilms tumor.
  • A syndrome of multiple defects characterized primarily by umbilical hernia (hernia, umbilical); macroglossia; and gigantism; and secondarily by visceromegaly; hypoglycemia; and ear abnormalities.
  • A syndrome of overgrowth of prenatal onset, advanced bone age, retarded psychomotor development, widened distal long bones, camptodactyly, and distinctive craniofacial appearance marked by large ears, broad forehead, hypertelorism, and long philtrum. Weaver syndrome is considered a variant of the marshall-smith syndrome but, according to some authors, these are separate entities with share some common features, including are abnormal bone maturation, accelerated growth, and delayed development but differ in their craniofacial dysmorphism. Widened middle and proximal phalanges, failure to thrive, craniofacial abnormalities (small face, prominent eyes, blue sclera, flat nose with anteverted nares, choanal atresia, and glossoptosis). Respiratory disorders, hypertrichosis, and early death uniquely characterize the marshall-smith syndrome. A syndrome marked by symptoms similar to those in the weaver syndrome with hyperprogesteronemia and maternal luteoma and one with cleft lip, accessory nipples, pectus excavatum, bifid xiphoid process, abnormal vertebral bodies, and inflexible right thumb are referred to as the weaver-like syndrome.
  • Congenital or postnatal overgrowth syndrome most often in height and occipitofrontal circumference with variable delayed motor and cognitive development. Other associated features include advanced bone age, seizures, neonatal jaundice; hypotonia; and scoliosis. It is also associated with increased risk of developing neoplasms in adulthood. Mutations in the nsd1 protein and its haploinsufficiency are associated with the syndrome.
  • Enlarged tongue, omphalocele and other umbilical abnormalities, cytomegaly of the adrenal cortex, hyperplasia of gonadal interstitial cells, renal hyperplasia with medullary dysplasia, pancreatic hyperplasia, visceromegaly, and hypoglycemia with various neoplastic diseases and other disorders.
  • Increased birth weight with excessive growth during the first four years of life, macrocephaly, characteristic facial features, nonprogressive cerebral disorder and mental retardation.
Present On Admission
POA Help
"Present On Admission" is defined as present at the time the order for inpatient admission occurs — conditions that develop during an outpatient encounter, including emergency department, observation, or outpatient surgery, are considered POA.
  • Q87.3 is considered exempt from POA reporting.
